What is HCV genotyping test?

What is HCV genotyping test?

HCV can be diagnosed by the detection of the anti-HCV antibody in the serum or plasma samples, where a non-reactive result is considered as absence of HCV infection. Further, to declare an HCV infection as active infection, it needs to be confirmed by HCV RNA test.

What is the normal range of HCV test?

Normal range for this assay is “Not Detected”. The quantitative range of this assay is 10 – 100,000,000 IU/mL (1.0 – 8.0 log IU/mL). LLoQ values do not apply to diluted specimens.

What is HCV Ab W RFLX verification?

Hepatitis C Antibody with Reflex to HCV RNA,PCR w/Reflex to Genotype, LiPA – Hepatitis C Virus (HCV) is the major cause of hepatitis. Making positive HCV Ab tests reflex to confirmatory molecular testing is necessary to confirm active HCV infection.

How much does genotype test cost?

The cost of genetic testing can range from under $100 to more than $2,000, depending on the nature and complexity of the test. The cost increases if more than one test is necessary or if multiple family members must be tested to obtain a meaningful result. For newborn screening, costs vary by state.

What is the HCV genotype test used for?

This test is used to determine appropriate antiviral therapy by identifying major HCV genotypes and differentiating between genotype 1 subtypes 1a and 1b. This test also helps determine whether to test for resistance-associated substitutions. Determine appropriate antiviral therapy in patients with chronic hepatitis C virus (HCV) infection

What is the CPT code for HCV genotype 1 NS5A?

If HCV Genotype, LiPA is Genotype 1, Genotype 1a, or Genotype 1a/1b, then Hepatitis C Viral RNA Genotype 1 NS5a Drug Resistance will be performed at additional charge (CPT code (s): 87902).

What are the different genotypes of hepatocellular carcinoma (HCV)?

HCV has 6 main genotypes, designated 1 through 6. In the United States, genotype 1 is the most common ( Table 1 ). 3 Genotype 1 includes 2 clinically relevant subtypes: 1a and 1b.

What are the AASLD/IDSA guidelines on Ras testing for hepatitis C (HCV)?

AASLD/IDSA HCV guidelines 2 and the prescribing information for select DAAs 6,11 recommend NS5A RAS testing, in certain circumstances, before using these DAA regimens to treat patients infected with HCV genotypes 1a or 3.
