Test Details
Methodology
Electrochemiluminescence (ECL)
Result Turnaround Time
6 - 12 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
This test is used for C-peptide measurement.
Limitations
This assay has a lower limit of quantitation of 0.004 ng/mL.
Specimen Requirements
Specimen
Serum (preferred) or plasma
Volume
1 mL
Minimum Volume
0.3 mL (Note: This volume does not allow for repeat testing.)
Container
Gel-barrier tube, red-top tube or lavender-top (EDTA) tube
Collection Instructions
Serum or plasma must be separated from cells within 45 minutes of venipuncture. Submit specimen in a plastic transport tube. Freeze plastic transport tube (preferred) or refrigerate. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
Storage Instructions
Freeze (preferred) or refrigerate. Stable at room temperature for one day or refrigerated for seven days. Stable for 348 days frozen. Freeze/thaw cycles: x6.
