Reference Range:

Negative

Analytical range in log10 values:
  Log IU (15-100,000,000 IU/mL non-log transformed values)

Positive results less than 15 IU/mL will be reported as "POS <1.18 LOG 
IU", "POS <15 IU/mL" and negative results will be reported as "Not 
detected".

Methodology:

PCR amplification; Cobas HCV Test (Roche Diagnostics, Inc.)

Instructions:

Record draw time.

All collection tubes need to be processed within 24 hours of 
collection.  If specimens cannot reach the Microbiology laboratory at 
UIDL within the 24 hours, process as follows:

Centrifuge for 20 minutes at 800-1600 x g.  Aseptically enter the tube
and aliquot into sterile tubes.  Transport to the laboratory on ice 
within 24 hours.

Sample Processing:

Within 24 hours of collection, centrifuge at 800-1600 x g for 10 minutes.
Label transport tube with two patient identifiers, date and time of collection.
Maintain sterility and forward promptly to lab.
Specimen should be collected and packaged as close to shipping time as possible.
