Interpreting HBV Quant. results
- Linear reporting range of the assay is 20 – 1.7 x 108 IU/mL.
- Conversion factor: 1 IU/mL = 5.82 copies / mL.
The hepatitis B virus DNA quantification, also known as the viral load test, is a blood test that measures the amount of hepatitis B virus DNA (viral load) in the blood of chronically infected patients. The blood is tested using a Polymerase Chain Reaction (PCR) technique.
What is a low viral load for hepatitis B?
In particular, patients with serum HBV DNA levels ≥ 2000 IU/mL at study entry have an increased risk of developing HCC over time. In contrast, those with HBV DNA levels < 2000 IU/mL are usually designated as low viral load patients.
What is HBV DNA PCR test?
The HBV DNA test is performed on a blood sample using a Polymerase Chain Reaction (PCR) technique that rapidly generates HBV DNA fragments so they can be measured. Today, viral load is usually measured using international units per milliliter (IU/mL).
What is HBV DNA qualitative test?
This test is conducted on patients who have been diagnosed with chronic Hepatitis B. It helps monitor the condition and also monitor the response of the patient towards anti-HBV therapy. Test type. Blood.
The results of a viral load test are described as the number of copies of HIV RNA in a millilitre of blood. But your doctor will normally just talk about your viral load as a number. For example, a viral load of 10,000 would be considered low; 100,000 would be considered high.
What is a good viral load count?
What the Results Mean. A high viral load is generally considered about 100,000 copies, but you could have 1 million or more. The virus is at work making copies of itself, and the disease may progress quickly. A lower HIV viral load is below 10,000 copies.
How do you read Hep B test results?
For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
People on anti-retroviral treatment who fail to maintain viral load below 5,000 copies are almost two and a half times more likely to become ill or die within 12 months than people who maintain viral load below 500 copies.
Viral load is the term used to describe the amount of HIV in your blood. The more HIV there is in your blood (and therefore the higher your viral load), then the faster your CD4 cell count will fall, and the greater your risk of becoming ill because of HIV.
What does log IU mL mean?
log IU/mL) indicates that HCV RNA is detected, but the HCV RNA level present cannot be quantified accurately below this lower limit of quantification of this assay. When clinically indicated, follow-up testing with this assay is recommended in 1 to 2 months.
How is the HBV DNA test performed?
The HBV DNA test is performed on a blood sample using a Polymerase Chain Reaction (PCR) technique that rapidly generates HBV DNA fragments so they can be measured. Today, viral load is usually measured using international units per milliliter (IU/mL).
To compare apples to apples, your viral load (HBV DNA) during your first test was around 498 IU/mL (there are about 5.6 copies in every international unit) and now your viral load is 272 IU/mL. Bottom line, your viral load has stayed the same, and is very low, which is excellent news.
The viral load test measures the amount of HIV virus in your blood. It is the preferred way to monitor how HIV treatment is working.
What is the range of viral load on a log scale?
The range of viral load is so wide that results are often given as results from a logarithmic (log) scale. This is an easier way to deal with very large and very small numbers at the same time. Less than 50 copies/mL for most people on treatment is 1.7 logs.
