Syphilis Blood Test. Prices, Reviews, Ratings
Venereal diseases are a modern scourge. Conditions like syphilis, gonorrhea, AIDS, donovanosis, and chlamydia cause irreparable harm and serious consequences. While treatable, their therapeutic success hinges on timely detection of inflammation sources.
Blood tests and tissue analysis (e.g., hard chancre, regional lymph nodes) help specialists determine treatment strategies for syphilis pathogens. These tests require specialized facilities and proper equipment.
Many believe identifying syphilis or other STDs is straightforward. In reality, these diseases can be nearly asymptomatic, with health declines signaling advanced stages. A single blood test may not suffice; additional diagnostics are often ordered based on patient history.
Importance and Types of Syphilis Tests
Syphilis is transmitted sexually or through direct contact with an infected person’s blood or secretions. Media often downplay its severity, portraying it humorously. Yet, syphilis is a deadly disease, causing irreversible nervous system and organ damage in late stages.
Syphilis blood tests are quick and routine but critical for timely treatment initiation. Despite awareness, people often delay testing until symptoms appear, such as:
- skin rashes;
- painful genital ulcers;
- lymph node enlargement.
Indirect signs like headaches, fever, hair loss, or broad condylomas may also suggest syphilis, necessitating testing.
Blood tests are mandatory for job applications, pregnancy registration, surgeries, and incarceration. Screening large populations aims to detect syphilis early, protecting others from infection.
A dermatovenereologist’s exam alone often isn’t enough. Common tests include microscopic smear/scraping analysis, amniotic fluid testing in pregnancy, and ulcer/skin sampling. Blood isn’t studied microscopically for syphilis.
A positive result confirms syphilis, but a negative one doesn’t guarantee health. Suspected cases prompt specific confirmatory tests.
Blood Collection for Syphilis Testing
Most adults have undergone blood tests. Syphilis’s contagiousness makes testing mandatory for public-facing roles (trade, schools, healthcare). Its prevalence has normalized the procedure.
Key considerations: Timing is critical—testing immediately after potential exposure is a common error. Consult a doctor for accurate scheduling, typically days post-contact.
For precise results, avoid fried foods pre-test to prevent serum opalescence from elevated cholesterol.
Additional recommendations:
- List all medications taken during potential exposure (antibiotics, anti-inflammatories, hormones);
- Avoid alcohol and nicotine 24 hours prior;
- Fast 8–10 hours before testing.
Venous blood is typically used, with spinal fluid rarely tested.
Indications
Syphilis isn’t only sexually transmitted; household transmission occurs too. Regular blood tests are vital, as early stages may be asymptomatic, surprising both the infected and their families.
Beyond obvious reasons (pregnancy, military service, high-contact jobs), testing is essential for donors, children of suspected carriers, and high-risk professions.
Test Interpretation
Multiple tests are required. A negative result isn’t definitive, with a 10% error margin due to external or internal factors.
Causes of false positives/negatives:
- Coexisting endocrine or cardiovascular diseases (endocarditis, diabetes);
- Infectious conditions (viral hepatitis, tuberculosis, mononucleosis).
Lab specialists interpret results. Syphilis is confirmed by specific antibody levels using:
Non-specific serological tests:
- Microprecipitation reaction (MR): Antibody titers of 1:2–1:320 from finger blood a month post-exposure;
- Wasserman reaction (RW): Titers of 1:2–1:800, tested 5–6 weeks post-contact.
Specific serological tests:
- Immunofluorescence reaction (IFR): 1–4 “+” signs in venous/capillary blood;
- Passive hemagglutination (PHA): Blood mixed with rooster/sheep erythrocytes shows clumping;
- Enzyme immunoassay (EIA): Detects IgA, IgM, IgG antibodies;
- Treponema immobilization test (TIT): >50% immobilization of Treponema pallidum.
Initial tests rarely confirm syphilis; repeat or additional tests are often needed.
