Скачать или смотреть SPECIFIC AND NON SPECIFIC TEST FOR SYPHILIS or Trepenoma pallidum

A bacterial infection usually spread by sexual contact that starts as a painless sore.
Syphilis develops in stages and symptoms vary with each stage.

The first stage involves a painless sore on the genitals, rectum, or mouth. After the initial sore heals, the second stage is characterized by a rash. Then, there is a symptom-free latent phase, which may last for years before the final stage occurs. This final stage can damage the brain, liver, nerves, eyes, or heart (gummas).

Syphilis is treated with penicillin.

FTA -ABS TEST

The Fluorescent Treponemal Antibody Absorption (FTA-ABS) test is a blood test used to confirm syphilis infection. It detects antibodies to the bacteria that cause syphilis, Treponema pallidum. A positive result often indicates a past or present syphilis infection, and it remains positive even after successful treatment.
Here's a more detailed explanation:
What it tests for:
The FTA-ABS test specifically looks for antibodies against Treponema pallidum, the bacteria that causes syphilis.
How it's used:
It's primarily used as a confirmatory test after a positive result from a screening test like the Rapid Plasma Reagin (RPR) or Venereal Disease Research Laboratory (VDRL) test.
How it works:
The test involves exposing a blood sample to treponemes (the bacteria) that have been fixed on a slide. If antibodies to the treponemes are present, they will bind to the treponemes and be detected using a fluorescent microscope.
Interpretation of results:
Positive result: Usually indicates past or present syphilis infection.
Negative result: Can be a sign that you don't have syphilis or that the infection is very early or has been effectively treated.
Limitations:
The FTA-ABS test remains positive even after successful treatment, so it's not used to monitor the effectiveness of therapy. It can also produce false-positive results in some individuals, such as those with lupus or other autoimmune conditions.
Other uses:
The FTA-ABS test can also be performed on cerebrospinal fluid (CSF) to detect neurosyphilis. A negative CSF FTA-ABS test essentially rules out neurosyphilis.
