Plasma - Spec Container:
Pearl white top (PPT) (EDTA + gel barrier material), lavender top (EDTA), or pale yellow top (ACD-B) tube - Alt Spec Type:
Serum - Alt Spec Container:
Gold top (SST) or red top (serum) tube - Pref Vol:
3.0 mL - Min Vol:
1.6 mL - Fasting:
No - Spec Collect:
Routine venipuncture - Spec Process:
IMPORTANT: Sample must be removed from cells within 6 hours of collection time
It is optimal to process samples immediately after collection; however, samples must be processed at least within 6 hours of collection time or they will be rejected
Separate plasma from whole blood by centrifugation at 800 to 1600 xg for 20 minutes at room temperature
Transfer plasma to a properly identified, sterile, polypropylene, screw-capped vial
Freeze and transport frozen - Spec Store Transport:
Frozen - Spec Stability:
Room temperature (20-30°C): Unacceptable
48 hours refrigerated (2-8°C)
42 days frozen (-20°C) – Do not use frost-free units that undergo repeated freeze/thaw cycles - Spec Reject:
Heparinized sample
Sample submitted in original collection tube - Methodology:
Polymerase Chain Reaction (PCR)
Transcription-Mediated Amplification (TMA) - Use:
Test is used for the Quantitative detection of Hepatitis C virus (HCV) RNA. This test combines PCR and TMA for the detection of the broadest range of HCV (5-69,000,000 IU/mL). - Reference Range:
HEPTIMAX™ HCV RNA
< 5 IU/mL
< 0.7 LogIU/mLNote:
In response to client requests, results > or = 1,000,000 are reported in a modified exponential notation. For example, a result of 1,000,000 would be reported as 1.00E6, and a result of 42,000,000 would be reported as 42.0E6.
Reportable Ranges:
5-69,000,000 IU/mL
0.70-7.84 Log IU/mL
The method used in this test is Real-Time RT-PCR of the 5' UTR of the HCV genome.
This test is performed using COBAS® Ampliprep/COBAS® Taqman® HCV Test Kit (Roche Molecular Systems, Inc.) - Day Run:
Mon-Fri - Time Reported:
4 days - Test Type:
INFECTIOUS ORGANISM
