A Chlamydia Trachomatis IgG test detects the presence of antibodies against the Chlamydia bacteria in the blood.These antibodies indicate a past or ongoing Chlamydia infection.While a positive result suggests exposure to Chlamydia, it does not necessarily mean an active infection as antibodies can persist after successful treatment. This test is often used to screen for Chlamydia in individuals with symptoms or risk factors, but its not as reliable as nucleic acid amplification tests (NAATs) for diagnosing active infections.

THE TPHA IS A SPECIFIC SEROLOGICAL TEST USED TO DIAGNOSE SYPHILIS, A SEXUALLY TRANSMITTED INFECTION CAUSED BY THE BACTERIUM TREPONEMA PALLIDUM. THE TEST DETECTS THE PRESENCE OF ANTIBODIES IN THE BLOOD THAT ARE SPECIFICALLY DIRECTED AGAINST TREPONEMA PALLIDUM.

THIS TEST USES AN ENZYME-LINKED IMMUNOSORBENT ASSAY (ELISA) TO DETECT ANTIBODIES TO THE HEPATITIS C VIRUS IN THE BLOOD.

THIS TEST USES AN ENZYME-LINKED IMMUNOSORBENT ASSAY (ELISA) TO SCREEN FOR ANTIBODIES TO HIV-1 AND HIV-2. THE PRESENCE OF THESE ANTIBODIES INDICATES A PAST OR PRESENT INFECTION WITH HIV. A POSITIVE RESULT REQUIRES CONFIRMATION WITH A MORE SPECIFIC TEST, AS THIS IS A SCREENING METHOD.

THIS TEST DETECTS THE HEPATITIS B SURFACE ANTIGEN (HBSAG) IN THE BLOOD. THE PRESENCE OF HBSAG INDICATES AN ACTIVE INFECTION WITH THE HEPATITIS B VIRUS. IT CAN BE A NEW, ACUTE INFECTION OR A CHRONIC INFECTION.

A POSITIVE VDRL (RPR) INDICATES AN ACTIVE OR RECENT SYPHILIS INFECTION. THE DILUTION TITER CAN BE USED TO MONITOR THE EFFECTIVENESS OF TREATMENT, AS THE TITER SHOULD DECREASE AFTER SUCCESSFUL THERAPY.

THE PRESENCE OF IGM ANTIBODIES TYPICALLY INDICATES A RECENT OR PRIMARY INFECTION WITH HSV-1 OR HSV-2.
