VWFX | Test | VWFX | von Willebrand Factor Activity, Plasma | von Willebrand Factor Activity, P | Latex Particle Enhanced Immunoassay |  |  |  | 1 | mL | See Coagulation Studies in Special Instructions.    Specimen Type: Platelet-poor plasma Collection Container/Tube: Light-blue top (citrate) Submission Container/Tube: Plastic vial [NAME]: 2 mL in 2 plastic vials each containing 1 mL Collection Instructions: 1. Specimen must be drawn prior to factor replacement therapy. 2. Spin down, remove plasma, and spin plasma again. 3. Freeze specimens immediately at < or =-40 degrees C, if possible. 4. Send specimens in the same shipping container. Additional Information: 1. Double-centrifuged specimen is critical for accurate results as platelet contamination may cause spurious results. 2. Each coagulation assay requested should have its own vial. 3. Tests for F8A / Coagulation Factor VIII Activity Assay, [NAME] and VWAG / von Willebrand Factor [NAME], Plasma are recommended in conjunction with [NAME] activity. | 0.5 mL | Hemolysis	Mild OK; Gross reject Thawing	Warm reject; Cold OK refreeze - note to lab Lipemia	Mild OK; Gross reject Icterus	NA Other	NA | 55-200%   Normal, full-term newborn infants may have mildly increased levels which reach adult levels by 90 days postnatal. Healthy, premature infants (30-36 weeks gestation) may have increased levels that reach adult levels by 180 days. Note: Individuals of blood group "O" may have lower plasma von Willebrand factor (VWF) activity than those of other ABO blood groups, such that apparently normal individuals of blood group "O" may have plasma VWF activity as low as 40% to 50%, whereas the lower limit of the reference range for individuals of other blood groups may be 60% to 70%. | Monday through Saturday | 1 day | 3 days | 1 | 85397 |  |  |  |  | Rochester

Specimen Type: Platelet-poor plasma Collection Container/Tube: Light-blue top (sodium citrate) Submission Container/Tube: Plastic vial [NAME]: 1 mL Collection Instructions:  1. Fasting. 2. Spin down, remove plasma, and spin plasma again. 3. Freeze specimen immediately at < or =-40 degrees C, if possible. Additional Information:  1. Double-centrifuged specimen is critical for accurate results as platelet contamination may cause spurious results. 2. Each coagulation assay requested should have its own vial. 3. Tests for F8A/9070 Coagulation Factor VIII Activity Assay, [NAME] and [NAME], Plasma are recommended in conjunction with ristocetin cofactor. 4. Coagulation testing is highly complex, often requiring the performance of multiple assays and correlation with clinical information. For that reason, we suggest ordering VWPR/83099 von Willebrand Profile. | 0.5 mL | Hemolysis	Mild OK; Gross reject Thawing	Warm reject; Cold OK-refreeze-note to lab Lipemia	Mild OK; Gross reject Icterus	NA Other	NA | Adults: 55-200% Note: Individuals of blood group "O" may have lower plasma von Willebrand factor (VWF) ristocetin cofactor activity than those of other ABO blood groups, such that apparently normal individuals of blood group "O" may have plasma VWF ristocetin cofactor activity as low as 40% to 50%, whereas the lower limit of the reference range for individuals of other blood groups may be 60% to 70%.   Normal, full-term newborn infants or healthy premature infants usually have levels in the adult range. | Monday through Friday; p.m. | 1 day | 7 days | 1 | 85245 |  |  | No | No
