Procalcitonin Test Reference Range Determination

Study Overview
=================
Brief Summary
-----------------
Prospective, single-centre study in healthy volunteers to establish a reference range for the RAMP Procalcitonin (PCT) test. The primary objective of this study is to establish the reference range for measurement of PCT levels using the RAMP Procalcitonin test.

Detailed Description
-----------------
Healthy volunteers who meet eligibility criteria and have provided informed consent will be enrolled in this study. Each participant will be required to donate 1 blood sample via standard venipuncture into an EDTA (lavender top) tube for testing on one occasion. The maximum trial duration for each participant is one visit/occasion. Sample collection will take place within a single clinical session. The maximum trial duration for each participant is one clinic session.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Procalcitonin value for healthy reference subjects | Procalcitonin value for each subject will be determined within 2 hours of phlebotomy. At study completion all data obtained will be compiled and a 95th percentile value determined. | Subjects will be followed for duration of one blood draw from one visit only; study enrollment will occur over 21 days. |
