5. Enzyme Immunoassay (EIA) Test

• EIA test is a commonly used blood test for screening and diagnosing in syphilis test.
• It detects the presence of antibodies against Treponema pallidum using enzyme-labeled antigens.
• EIA test offers high sensitivity, specificity, and rapid results, making it an efficient diagnostic tool for syphilis.

Enzyme Immunoassay (EIA) Test	Details
Also Known As	ELISA (Enzyme-Linked Immunosorbent Assay)
Purpose	Screening syphilis infection

Procedure	Blood sample collection and testing
Test Timing	A few hours
Test Price (INR)	300-1500
Result value	Positive or negative
Normal Value	Negative
Accuracy	High sensitivity and specificity
Interpretation	Positive results indicate the presence of antibodies, requiring further testing for confirmation.

The Enzyme Immunoassay (EIA) Test, also known as ELISA, is a blood test used for screening and diagnosing syphilis infection. It offers accurate results and aids in further confirmatory testing if positive.

 

6. Chemiluminescent Microparticle Immunoassay (CMIA) Test

• CMIA test is a modern and highly sensitive blood test used for syphilis diagnosis test.
• It utilizes chemiluminescent microparticles to detect antibodies against Treponema pallidum.
• CMIA test provides quick results, and excellent accuracy, and is widely used in clinical settings for syphilis screening and confirmation.
