The HIV Antigen/Antibodies Test is the recommended standard rapid test for routine HIV Screening. It typically sees quick results in just 1-2 business days and is one of the most affordable HIV tests available. The HIV Antigen/Antibodies test, also known as a 4th Generation HIV Test, looks for both antibodies to the HIV virus and the p24 Antigen which is specific to HIV. Antibodies to HIV typically begin to develop several weeks after exposure. In the majority of people, these antibodies will be detectable by 12 weeks from the point of exposure. In some people, antibodies may be detectable as early as 4 weeks from exposure. The p24 Antigen is a viral protein which makes up the majority of the HIV viral core (capsid). P24 Antigen levels are typically highest a few weeks after exposure and drop to undetectable levels during the time when antibodies begin to develop. The combination of screening for both antibodies and antigen allow this test to detect a significantly higher number of early infections than previous generations of HIV screening.
Description: QuantiFERON-TB Blood Test The QuantiFERON-TB Blood Test is used to aid in the diagnosis of both latent and active infections with the bacteria that causes Tuberculosis (TB) . This test is one of only 2 blood tests for TB approved by the FDA. Tuberculosis is a bacterial disease that typically affects the lungs. TB Bacteria is spread through the air from one person to another. While TB is not as common in the United States as it once was, there is the still a risk posed by TB infection. It is estimated that 11 million people in the US have a latent Tuberculosis infection (LTBI). Diagnosis and treatment of LTBI can prevent it from progressing to active Tuberculosis.
