Aptima HCV Quant Dx Assay (CE-IVD)

The Aptima HCV Quant Dx assay is CE-IVD certified for the confirmation of active infection and viral load monitoring on the fully automated Panther system. 

  • Ultrasensitive, highly precise performance over a wide linear range, across all major genotypes.
  • Validated sample dilution protocols allow you to run samples with as little as 240µL (for viral load use only).
  • Minimize operator hands-on time with true sample-to-result automation on the Panther system.

This assay is not available for sale in the U.S. Please contact your local sales representative for product availability.


The Aptima HCV Quant Dx assay is an in vitro nucleic acid amplification test (NAAT) for the detection and quantitation of HCV RNA in fresh and frozen human serum or plasma on the fully automated Panther system. The Aptima HCV Quant Dx assay is indicated for use as an aid in the diagnosis of HCV infection and for use as an aid in the management of HCV infected patients undergoing HCV antiviral drug therapy.

  • Streamline and simplify HCV testing within your lab with the versatility of a single assay for both confirmation of active infection AND viral load monitoring
  • Quantify HCV RNA—across all major genotypes—with ultrasensitivity and high precision over a wide linear range. 
  • Strategic design with three levels of protection:
    • Redundant target capture oligos to protect against potential mutations. 
    • Longer oligos for extra protection against single base mismatches.
    • Multiple amplification primers for broad genotype coverage.

Diagnostic and Confirmatory Testing of HCV

The Aptima HCV Quant Dx assay is indicated for use as an aid in the diagnosis of HCV infection. The assay can be used to confirm active HCV infection in patients with a positive HCV antibody result. Detection of HCV RNA indicates that the virus is replicating and, therefore, is evidence of active infection.

Management of HCV infected patients

The Aptima HCV Quant Dx assay is indicated for use as an aid in the management of HCV infected patients undergoing HCV antiviral drug therapy.1 The assay measures HCV RNA levels at baseline, during treatment, and after treatment to determine sustained virological response (SVR).2 The results from the Aptima HCV Quant Dx assay must be interpreted within the context of all relevant clinical and laboratory findings. 

The Aptima HCV Quant Dx assay is not intended for use as a screening test for the presence of HCV in blood or blood products.


Ultrasensitivity for Treatment Management

The Aptima HCV Quant Dx assay’s Limit of Detection (LoD) is 4.3 IU/mL in plasma (3.9 IU/mL in serum).

LoD Across HCV Genotypes 1-6


Lower Limit of Quantitation (LLoQ)

The LLoQ of the Aptima HCV Quant Dx assay is 10 IU/mL.

Confidence in Performance Across a Broad Linear Range

The linear range was established by testing panels of HCV Armored RNA diluted in HCV-negative human plasma and serum.  The linear range of the Aptima HCV Quant Dx assay is 1.0 to 8.0 log IU/mL.

Linearity Across Genotypes 1-6

Reliable Quantitation

In addition to accurate quantitation, the Aptima HCV Quant Dx assay offers precise quantitation across the linear range. Precision is maintained in plasma samples with low-viremia with narrow CV of 11.34% in samples with only 1.23 log IU/mL.
