Glossary of Terms
 
Amine test

The amine test (or "whiff" test) is performed by adding a drop of 10% KOH on a vaginal fluid specimen placed on a slide and mixing with a wooden applicator or swab. Sniff for a "fishy" odor. In the presence of bacterial vaginosis and sometimes trichomoniasis, the fishy odor is due to the release of volatile amines.

Non-treponemal tests

Serologic tests for syphilis that measure IgM and IgG antibody directed against a cardiolipin-lecithin-cholesteral antigen. These tests are not specific for T. pallidum, and need to be confirmed with a treponemal test for initial diagnosis of syphilis. Commonly used tests include VDRL (Venereal Disease Research Laboratory), RPR (Rapid Plasma Reagin), TRUST (Toluidine Red Unheated Serum Test) and USR (Unheated Serum Reagin). Sensitivity varies with stage of syphilis infection. False negative non-treponemal test results occur in up to 25% of primary syphilis cases; the non-treponemal tests are almost 100% sensitive in secondary syphilis. They are inexpensive and easy to perform. The result can be quantitated, so that these test results can be used evaluate for possible treatment failure or re-infection.

Treponemal tests

Serologic tests for syphilis that measure antibody (IgM and IgG) directed against T. pallidum. These tests are specific to T. pallidum, and are used to confirm reactive non-treponemal test results for an initial diagnosis of syphilis. Commonly used tests include TP-PA (Treponema pallidum-particle agglutination), FTA-ABS (fluorescent antibody absorption) and Captia EIA (enzyme immunoassay). The test result is qualitative, and once reactive, usually remains so for life. Hence these tests are used to confirm a reactive non-treponemal result in making the diagnosis of syphilis, but are not useful in evaluating response to treatment or possible re-infection.

Uterine or adnexal tenderness, or cervical motion tenderness

Here is how to perform the pelvic examination:
Palpate the cervix, noting its position, shape, consistency, regularity, mobility, and tenderness. Normally, the cervix can be moved somewhat without pain. Palpate the fornices 180º for abnormalities, pain, or other unusual findings (i.e., foreign body, retained tampon).
Place your other hand on the abdomen about midway between the umbilicus and the symphisis pubis. While you elevate the cervix and uterus with your pelvic hand, slowly press your abdominal hand down, trapping the uterus between your two hands. Assess the size, shape, consistency, position, and mobility. Identify any tenderness or masses. Slide both fingers of your pelvic hand into the anterior fornix and palpate the body of the uterus between your hands. If you are unable to identify the uterus with either of these maneuvers, the uterus may be tipped posteriorly retroverted. In this case, slide your pelvic fingers into the posterior fornix and identify the uterus abutting against your fingers.
Place your abdominal hand on the right lower quadrant, your pelvic hand in the right lateral fornix. Press your abdominal hand in and down, trying to push the adnexal structures toward your pelvic hand. Identify the right ovary or any adjacent adnexal structures between your fingers, if possible, and note their size, shape, consistency, mobility, and tenderness. Repeat the procedure on the left side. Ovaries are normally approximately the size of an almond (<3 cm) and somewhat tender. They are usually palpable in slender, relaxed women, but are difficult or impossible to recognize in others who are obese or poorly relaxed.
