Question

Sabin Feldman dye test is used for diagnosis of which of the following condition:

• A. Botulism
• B. Toxoplasmosis
• C. Sarcoidosis
• D. Yellow fever

Answer 1

The Correct Option is B

The Sabin Feldman dye test is a specific serological test used in the field of microbiology. It is employed to diagnose Toxoplasmosis, a disease caused by the Toxoplasma gondii parasite. This test functions by assessing the presence of antibodies against the Toxoplasma antigen in a patient's serum. In detail, the test procedure involves mixing the patient's serum with a suspension of live Toxoplasma organisms and a blue dye. If the patient's serum contains antibodies against the parasite, they will bind to the organisms, preventing them from taking up the dye. This indicates a positive result, confirming exposure to the parasite and, consequently, an infection.
