BDNA test
BDNA Test
The BDNA Test (pronounced: B-D-N-A Test), also known as Branched DNA Test, is a type of molecular diagnostic test used to measure the amount of specific viral or bacterial genetic material in a patient's blood sample. This test is often used to monitor the progression of viral infections such as HIV and Hepatitis C.
Etymology
The term "BDNA" is an acronym for "Branched DNA". This name is derived from the unique structure of the DNA probes used in the test, which resemble a tree with many branches. The "test" part of the name refers to the diagnostic procedure itself.
Procedure
The BDNA Test involves the collection of a blood sample from the patient. This sample is then treated with a series of enzymatic reactions that amplify the target genetic material. The amplified material is then detected and quantified using a specialized spectrophotometer.
Related Terms
- Viral Load: The amount of virus in a patient's blood, often measured using the BDNA Test.
- Quantitative PCR: Another type of molecular diagnostic test that can be used to measure viral load.
- Antiretroviral Therapy: A treatment strategy for viral infections that often involves monitoring viral load using tests like the BDNA Test.
Advantages and Limitations
The BDNA Test is highly sensitive and can accurately measure low levels of viral genetic material. However, it is not able to distinguish between different strains of a virus, and it may not be as effective for detecting certain types of bacteria.
