DLO Direct™ offers several tests that can help detect infectious diseases.


The STD panel is a group of tests used to screen for common sexually transmitted diseases including herpes, syphilis, gonorrhea and chlamydia. These tests screen for the antibodies the body produces in response to the infection.


The gonorrhea/chlamydia test is to screen for or diagnose a gonorrhea and/or chlamydia infection. Testing for Chlamydia trachomatis and Neisseria gonorrhoeae (gonorrhea) is generally done simultaneously as the two organisms have similar clinical presentations. A definitive diagnosis is important since the symptoms of chlamydia can resemble those of gonorrhea and the two infections require different antibiotic treatment.


Herpes simplex virus testing is performed to detect herpes antibodies, an indication of a current or previous exposure to herpes. Genital herpes is a sexually transmitted disease caused by two types of viruses. The viruses are called herpes simplex type 1 (HSV-1) and herpes simplex type 2 (HSV-2).


Syphilis is an infection caused by the bacteria Treponema pallidum and is most often spead by sexual contact. Syphilis testing screens for the presence of antibodies the body produces in response to the bacteria.


The QuantiFERON® TB Gold test is a blood test for tuberculosis. Unlike a typical skin test, which requires two visits, one for the skin scratch and a second for a reading, the QuantiFERON® TB test uses a blood sample so only a single visit is needed. The skin test can also show “false positive” results.
