STD Testing Package (Full PDF) Results By Laboratory

Sexual health testing packages from Health Testing Centers include tests for chlamydia, gonorrhea, HIV, herpes (types 1 and 2), and syphilis. Expanded STD packages also include tests for hepatitis B and C.

Below you will find disease specific STD testing sample results with explanations, interpretations and relevant ranges. Linked to the corresponding illustrative sections below, result examples include:

Chlamydia STD Test Results

STD testing for chlamydia is ideally performed using a nucleic acid amplification (NAA) test on a urine sample. NAA testing for chlamydia is the most sensitive and effective form of STD testing for chlamydia. Chlamydia is currently the most commonly reported STD in the U.S.

Negative reference range for Chlamydia, Gonorrhea and Trichomoniasis: LabCorp - Negative; Quest Diagnostics: Not Detected (means a negative result).
Positive reference range for Chlamydia, Gonorrhea and Trichomoniasis: LabCorp - treatment is needed; Quest Diagnostics - Detected (means a positive result and treatment is needed).

Gonorrhea STD Test Results

STD testing for gonorrhea is performed using the same nucleic acid amplification urine test used to detect chlamydia. This combination STD test is extremely specific and generates results that are clearly "positive" or "negative" for both the gonorrhea and chlamydia infections.

Hepatitis STD Test Results

STD testing for hepatitis is specific for the three most common forms of the infection: hepatitis A, hepatitis B and hepatitis C. Testing is done a a blood sample and detects / measures the level of antibodies. If antibodies are present in the blood it indicates that a person has been exposed to the hepatitis infection.

Negative reference range for Hepatitis A and B antibody and antigen: LabCorp - Negative; Quest Diagnostics - Non-Reactive.
Positive reference range for Hepatitis A and B antibody and antigen: LabCorp - Positive; Quest Diagnostics - Reactive.
Negative reference range for Hepatitis C antibody: LabCorp - if your result is less than 0.9 (<0.9) your result is negative; Quest Diagnostics - if your result is less than 1.00 (<1.00) your result is Non-reactive, which is negative.
Positive reference range for Hepatitis C antibody: LabCorp - if your results is greater than 0.9 (>0.9) your results is positive. If your result is between 0.8 and 0.9 your result is indeterminate and further testing may be needed; Quest Diagnostics - if your result is greater than 1.00 (>1.00), your results is Reactive, which is positive.

Herpes STD Test Results

STD testing for herpes measures the amount of antibodies present in the blood for herpes simplex virus 1 and 2. A negative result indicates that no herpes antibodies were present in the blood and that the person has not been exposed to the virus. Exposure to herpes 1 is extremely common and often occurs initially in childhood as a common cold sore. Having herpes 2 antibodies in the blood indicates that the person has been exposed to the STD, even if no symptoms are present.

Negative reference range for HSV 1: LabCorp - if your result is showing less than 0.91 (<0.91) then the result is negative; Quest Diagnostics - if your result is showing less than 0.90 (<0.90) then the result is negative.
Positive reference range for HSV 1: LabCorp - if your result is greater than 1.09 (>1.09), then your result is positive and treatment may be necessary; Quest Diagnostics - if your result is greater than 1.09 (>1.09), then your result is positive and treatment may be necessary.
Equivocal Result: if your result is between 0.91 and 1.09 you may have an early infection which is not fully detectable at the time of testing. You may want to retest around 3 months after exposure.

HIV STD Test Results

STD testing for HIV can be done using a few different blood tests depending upon your needs and concerns. The standard HIV test detects HIV antibodies in the blood and is effective typically after 90 days from possible exposure. Any early detection STD test such as Early HIV Detection (DNA PCR) Test uses polymerase chain reaction to detect HIV proviral DNA. An early detection STD test can produce a positive or negative result after approximately 28 days from exposure.

Negative reference range for HIV: LabCorp - Non-Reactive; Quest Diagnostics - Non-Reactive.
Positive reference range for HIV: LabCorp -Reactive; Quest Diagnostics - Reactive.

Syphilis STD Test Results

STD testing for syphilis is done through a rapid plasma reagin (RPR) blood test. This type of STD test detects antibodies in the blood that are "non-specific" for the bacteria that causes syphilis, treponema pallidum. The antigens measured are actually released by cells that have been damaged by the bacteria.

Negative reference range for Syphilis/T.Pallidium: LabCorp - Negative; Quest Diagnostics - Negative.
Positive reference range for Syphilis/T.Pallidium: LabCorp - Positive; Quest Diagnostics - Positive. Immediate treatment is needed in the event of a positive syphilis result.
