Collection container (including preservatives):
EDTA Blood tube
Specimen type: EDTA Blood/Plasma
Collection: Freshly drawn whole blood in
Specimen transport: Clinical samples should be
collected into a sterile leak-proof container in a sealed plastic
bag. Appropriate hazard labelling according to local policy should
be applied. Specimens should be transported and processed as soon
as possible, complying with postal and transport regulations. If
processing is delayed, refrigeration is preferable to storage at

Special precautions: Haemolysed specimens can
be inhibitory; where this is unavoidable, such as with post-mortem
samples, the laboratory should be contacted (0161-276-8843).
Plasma should be stored at 4°C and dispatched as soon as
possible. An additional 3mL fresh whole blood in EDTA should be
sent if the initial HCV PCR is positive.
Measurement units: IU/mL
Dynamic range: The dynamic range for this assay
is 12-108 copies/mL
Turnaround time: The results of all tests will
be available within 3-4 working days after receipt of the specimen
in the laboratory, and may be available within 24 hrs by prior
arrangement with the laboratory.
Clinical decision points: Not applicable
Factors known to significantly affect the
results: Haemolysed specimens can be inhibitory; where
