Question

Which of the following laboratory tests are utilized to confirm diagnosis of HIV?

1) ELISA
2) Western blot
3) PCR
4) All of the above

Answer 1

ELISA, Western blot, and PCR are laboratory tests that can be used to confirm the diagnosis of HIV.

Step-by-step explanation:

To confirm a diagnosis of HIV, multiple laboratory tests can be utilized, including ELISA, Western blot, and PCR. ELISA is an initial screening test that detects the presence of HIV antibodies in the blood. However, a positive ELISA result needs confirmation, which is typically done using a Western blot, which identifies specific peptides from the HIV virus. PCR, or polymerase chain reaction, is another test that can be used to detect the presence of HIV sequences in the blood. It is important to note that all three tests are commonly used in combination to ensure a accurate diagnosis.
