Product code: 2 LCO, Platelet factor 4 radioimmunoassay GGN, Plasma, Coagulation Control 4. Panel: Hematology (81) H. Intended Use: 1. Intended use(s): HemosIL HIT-Ab(PF4-H) is a qualitative, fully automated, latex enhanced immunoassay for the detection of anti-platelet factor 4/heparin (PF4/H) antibodies. The assay is for use in human 3.2% or 3.8% citrated plasma on the ACL TOP® Family of instruments in a laboratory setting. The result provided by the assay should be interpreted as either positive or negative based on the assay cut-off (1.0 U/mL). The positive or negative result aids in determining the risk for heparin induced thrombocytopenia (HIT) when used in conjunction with other laboratory and clinical findings. Anti-PF4/Heparin antibodies are commonly found in patients with HIT. For use in adult population suspected of HIT. Not for use in isolation to exclude HIT. HemoslL HIT-Ab(PF4-H) Controls are for the Quality Control of the HemosIL HIT-Ab(PF4- H) assay as performed on the ACL TOP® Family of instruments. For prescription use. 2.

Device Description: The HemosIL HIT-Ab(PF4-H) kit is a latex particle enhanced immuno-turbidimetric assay to detect total anti‐PF4/Heparin antibodies found in HIT patients. A monoclonal 3 antibody that mimics human HIT antibodies is coated onto latex particles. The HemosIL HIT-Ab(PF4-H) kit consists of: Latex Reagent: Suspension of polystyrene latex particles coated with purified mouse monoclonal anti-PF4-Heparin in Tris buffer, containing bovine serum albumin, stabilizers and preservative. Stabilizer: PBS buffer containing bovine serum albumin, stabilizers and preservative. Complex: Solution of PF4-PVS complex (PF4 from human platelets complexed to PVS), in PBS buffer containing bovine serum albumin, stabilizers and preservative. Contains 0.02% Bronidox™ as a preservative. Calibrator: Lyophilized solution of a monoclonal anti- PF4-Heparin antibody in Tris buffer containing bovine serum albumin, stabilizers and preservative. Controls: The Low and High HIT‐Ab(PF4‐H) Controls are prepared by means of a dedicated process and contain different concentrations of humanized monoclonal anti‐PF4‐Heparin human IgG. • Low HIT Control: Control intended for the assessment of precision and accuracy of the assay at PF4/H antibody levels at or below the cut‐off. • High HIT Control: Control intended for the assessment of precision and accuracy of the assay at abnormal PF4/H antibody levels.

Purpose for Submission: Clearance of a new device C. Measurand: Coagulation factors (intrinsic and extrinsic pathway) and platelet aggregation D. Type of Test: Whole blood hemostasis E. Applicant: Coramed Technologies, LLC F. Proprietary and Established Names: CORA® (Coagulation Resonance Analysis) System The system includes the CORA instrument and the following reagents: CK (Citrated Kaolin), CRT (Citrated RapidTEG), CKH (Citrated Kaolin with Heparinase), and CFF (Citrated Functional Fibrinogen). G. Regulatory Information: 1. Regulation section: 21 CFR 864.5425, Multipurpose system for in vitro coagulation studies 21 CFR 864.5700, Automated platelet aggregation system 2. Classification: Class II 3. Product code: 2 JPA, System, Multipurpose For In Vitro Coagulation Control GGN, Plasma, Coagulation Control 4. Panel: Hematology (81) H. Intended Use: 1. Intended use(s): CORA Hemostasis System: The CORA System is intended for in vitro diagnostic use to provide semi-quantitative indications of the hemostasis state of a blood sample. The CORA System records the kinetic changes in a venous sample of 3.2% citrated whole blood as the sample clots, and retracts in real time. The system output consists of a table of numerical values for parameters R, K, Angle, MA, and FLEV. The CORA System provides specific blood modifiers, in the form of reagents dried-in-place within CORA Cartridges. Results from the CORA analysis should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient's medical history, the clinical picture and, if necessary, further hemostasis tests. Citrated Multichannel Cartridge: The CORA System is intended for in vitro diagnostic use to provide semi-quantitative indications of the hemostasis state of a venous blood sample. The citrated Multichannel Cartridge, to be used with the CORA System instrument, contains four independent assays (CK, CRT, CKH and CFF), described below. The CK assay monitors the hemostasis process via the intrinsic pathway in 3.2% citrated whole blood specimens on the CORA System. Clotting characteristics are described by the functional parameters Clotting Time (R), Speed of Clot Formation (K and Alpha angle) and Maximum Clot Strength (MA). The CRT assay monitors the hemostasis process via both the intrinsic and extrinsic pathway in 3.2% citrated whole blood specimens on the CORA System. Clotting characteristics are described by the functional parameter Maximum Clot Strength (MA). The CRT MA parameter is equivalent to the CK MA parameter but the final MA value is reached more quickly using the CRT assay. The CKH assay monitors the effects of heparin in 3.2% citrated whole blood specimens on the CORA System. CKH is used in conjunction with CK, and heparin influence is 3 determined by comparing Clotting Times (R) between the two tests. The CFF assay monitors hemostasis of 3.2% citrated whole blood specimens in the CORA System after blocking platelet contribution to clot strength. Clotting characteristics are described by the functional parameters Maximum Clot Strength (MA) and the Estimated Functional Fibrinogen Level (FLEV). Results from the CORA analysis should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient’s medical history, the clinical picture and, if necessary, further hemostasis tests. Abnormal Wet Quality Control (WQC) Material: The CORA System is intended for in vitro diagnostic use to provide semi-quantitative indications of the hemostasis state of a venous blood sample. The Abnormal Wet Quality Control Material is to be used for monitoring the accuracy and precision of tests carried out on the CORA System. Results from the CORA analysis should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient’s medical history, the clinical picture and, if necessary, further hemostasis tests. 2. Indication(s) for use: The indication for CORA System use is with adult patients where an evaluation of their blood hemostasis properties is desired. Hemostasis evaluations are commonly used to assess clinical conditions in cardiovascular surgery and cardiology procedures to assess hemorrhage or thrombosis conditions before, during and following the procedure. 3.

Regulatory Information: 1. Regulation section: 21 CFR 866.3860 2. Classification: Class II 3. Product code: OUY - Trichomonas vaginalis nucleic acid amplification test system 4. Panel: 83 - Microbiology 2 H. Intended Use: 1. Intended use(s): The AmpliVue® Trichomonas Assay is an in vitro diagnostic test, uses isothermal amplification technology (helicase-dependent amplification, HDA) for the qualitative detection of Trichomonas vaginalis nucleic acids isolated from clinician-collected vaginal swab specimens obtained from symptomatic or asymptomatic females to aid in the diagnosis of trichomoniasis. 2. Indication(s) for use: Same as Intended Use 3. Special conditions for use statement(s): For prescription use only 4. Special instrument requirements: None I. Device Description: The AmpliVue® Trichomonas Assay is a self-contained disposable amplicon detection device that uses an isothermal amplification technology named Helicase-Dependent Amplification (HDA) for the detection of Trichomonas vaginalis in clinician-collected vaginal swabs from symptomatic and asymptomatic women. The assay targets a conserved multi-copy sequence of the T. vaginalis genomic DNA. The vaginal swab is eluted in a lysis tube, and the cells are lysed by heat treatment. After heat treatment, an aliquot of the lysed specimen is transferred into a dilution tube. An aliquot of this diluted sample is then added to a reaction tube containing a lyophilized mix of HDA reagents including primers specific for the amplification of a conserved DNA sequence only found in T. vaginalis. The assay includes an internal control for monitoring the integrity of the assay reagents and detection cassette as well as for monitoring HDA-inhibitors that may be present within the clinical specimens. The HDA reaction is asymmetric generating an excess of single-stranded DNA amplicons. The sequence specific capture probes as well as a biotinylated detection probe shared by both target and internal control bind to the corresponding single-stranded amplicons, forming dual labeled probe-amplicon hybrid. After completion of the HDA reaction, the reaction tube is transferred to a cassette for rapid detection and test result display. The dual-labeled probe-amplicon hybrid is detected by the lateral flow strip within the cassette. The bottom line captures the T. vaginalis amplicon and the top line captures the control amplicon. The biotin label binds the streptavidin-conjugated color particles for visualization and the test result is shown as a visible colored lines. 3 The cassette is comprised of two individual components: an amplicon cartridge that holds the running buffer and a single 0.2 mL thin wall reaction tube containing the amplified product; and the detection chamber which houses the amplicon cartridge and a vertical-flow DNA detection strip embedded into the cassette. The DNA detection strip is coated with different anti-hapten antibodies that serve as the T. vaginalis test (T) line and the control (C) line in the assay. A razor blade and a plastic pin located at the bottom of the detection chamber open the HDA reaction tube and the running buffer bulb when the handle of the cassette is closed. The mixture flows through a fiberglass paper connected to the DNA detection strip containing a fiberglass pad pre-loaded with streptavidin-conjugated color particles for color visualization. Detection of T. vaginalis DNA is reported whenever the T2 (Test line 2) is visible through the detection window of the cassette. The presence of T1 line is an invalid result for this assay and the test should be repeated with the lysed specimen. The presence of the C line is not required for positive results. No detection of T. vaginalis DNA is reported when only the C line is displayed. The assay is regarded as invalid when neither line is displayed. J. Substantial Equivalence Information: 1.

Panel: 83 - Microbiology 2 H. Intended Use: 1. Intended use(s): The AmpliVue® Trichomonas Assay is an in vitro diagnostic test, uses isothermal amplification technology (helicase-dependent amplification, HDA) for the qualitative detection of Trichomonas vaginalis nucleic acids isolated from clinician-collected vaginal swab specimens obtained from symptomatic or asymptomatic females to aid in the diagnosis of trichomoniasis. 2. Indication(s) for use: Same as Intended Use 3. Special conditions for use statement(s): For prescription use only 4. Special instrument requirements: None I. Device Description: The AmpliVue® Trichomonas Assay is a self-contained disposable amplicon detection device that uses an isothermal amplification technology named Helicase-Dependent Amplification (HDA) for the detection of Trichomonas vaginalis in clinician-collected vaginal swabs from symptomatic and asymptomatic women. The assay targets a conserved multi-copy sequence of the T. vaginalis genomic DNA. The vaginal swab is eluted in a lysis tube, and the cells are lysed by heat treatment. After heat treatment, an aliquot of the lysed specimen is transferred into a dilution tube. An aliquot of this diluted sample is then added to a reaction tube containing a lyophilized mix of HDA reagents including primers specific for the amplification of a conserved DNA sequence only found in T. vaginalis. The assay includes an internal control for monitoring the integrity of the assay reagents and detection cassette as well as for monitoring HDA-inhibitors that may be present within the clinical specimens. The HDA reaction is asymmetric generating an excess of single-stranded DNA amplicons. The sequence specific capture probes as well as a biotinylated detection probe shared by both target and internal control bind to the corresponding single-stranded amplicons, forming dual labeled probe-amplicon hybrid. After completion of the HDA reaction, the reaction tube is transferred to a cassette for rapid detection and test result display. The dual-labeled probe-amplicon hybrid is detected by the lateral flow strip within the cassette. The bottom line captures the T. vaginalis amplicon and the top line captures the control amplicon. The biotin label binds the streptavidin-conjugated color particles for visualization and the test result is shown as a visible colored lines. 3 The cassette is comprised of two individual components: an amplicon cartridge that holds the running buffer and a single 0.2 mL thin wall reaction tube containing the amplified product; and the detection chamber which houses the amplicon cartridge and a vertical-flow DNA detection strip embedded into the cassette. The DNA detection strip is coated with different anti-hapten antibodies that serve as the T. vaginalis test (T) line and the control (C) line in the assay. A razor blade and a plastic pin located at the bottom of the detection chamber open the HDA reaction tube and the running buffer bulb when the handle of the cassette is closed. The mixture flows through a fiberglass paper connected to the DNA detection strip containing a fiberglass pad pre-loaded with streptavidin-conjugated color particles for color visualization. Detection of T. vaginalis DNA is reported whenever the T2 (Test line 2) is visible through the detection window of the cassette. The presence of T1 line is an invalid result for this assay and the test should be repeated with the lysed specimen. The presence of the C line is not required for positive results. No detection of T. vaginalis DNA is reported when only the C line is displayed. The assay is regarded as invalid when neither line is displayed. J. Substantial Equivalence Information: 1.

Regulatory Information: 1. Regulation section: 21 CFR 866.3860 2. Classification: Class II 3. Product code: OUY - Trichomonas vaginalis nucleic acid amplification test system 4. Panel: 83 - Microbiology 2 H. Intended Use: 1. Intended use(s): The AmpliVue® Trichomonas Assay is an in vitro diagnostic test, uses isothermal amplification technology (helicase-dependent amplification, HDA) for the qualitative detection of Trichomonas vaginalis nucleic acids isolated from clinician-collected vaginal swab specimens obtained from symptomatic or asymptomatic females to aid in the diagnosis of trichomoniasis. 2. Indication(s) for use: Same as Intended Use 3. Special conditions for use statement(s): For prescription use only 4. Special instrument requirements: None I. Device Description: The AmpliVue® Trichomonas Assay is a self-contained disposable amplicon detection device that uses an isothermal amplification technology named Helicase-Dependent Amplification (HDA) for the detection of Trichomonas vaginalis in clinician-collected vaginal swabs from symptomatic and asymptomatic women. The assay targets a conserved multi-copy sequence of the T. vaginalis genomic DNA. The vaginal swab is eluted in a lysis tube, and the cells are lysed by heat treatment. After heat treatment, an aliquot of the lysed specimen is transferred into a dilution tube. An aliquot of this diluted sample is then added to a reaction tube containing a lyophilized mix of HDA reagents including primers specific for the amplification of a conserved DNA sequence only found in T. vaginalis. The assay includes an internal control for monitoring the integrity of the assay reagents and detection cassette as well as for monitoring HDA-inhibitors that may be present within the clinical specimens. The HDA reaction is asymmetric generating an excess of single-stranded DNA amplicons. The sequence specific capture probes as well as a biotinylated detection probe shared by both target and internal control bind to the corresponding single-stranded amplicons, forming dual labeled probe-amplicon hybrid. After completion of the HDA reaction, the reaction tube is transferred to a cassette for rapid detection and test result display. The dual-labeled probe-amplicon hybrid is detected by the lateral flow strip within the cassette. The bottom line captures the T. vaginalis amplicon and the top line captures the control amplicon. The biotin label binds the streptavidin-conjugated color particles for visualization and the test result is shown as a visible colored lines. 3 The cassette is comprised of two individual components: an amplicon cartridge that holds the running buffer and a single 0.2 mL thin wall reaction tube containing the amplified product; and the detection chamber which houses the amplicon cartridge and a vertical-flow DNA detection strip embedded into the cassette. The DNA detection strip is coated with different anti-hapten antibodies that serve as the T. vaginalis test (T) line and the control (C) line in the assay. A razor blade and a plastic pin located at the bottom of the detection chamber open the HDA reaction tube and the running buffer bulb when the handle of the cassette is closed. The mixture flows through a fiberglass paper connected to the DNA detection strip containing a fiberglass pad pre-loaded with streptavidin-conjugated color particles for color visualization. Detection of T. vaginalis DNA is reported whenever the T2 (Test line 2) is visible through the detection window of the cassette. The presence of T1 line is an invalid result for this assay and the test should be repeated with the lysed specimen. The presence of the C line is not required for positive results. No detection of T. vaginalis DNA is reported when only the C line is displayed. The assay is regarded as invalid when neither line is displayed. J. Substantial Equivalence Information: 1.
