WIDAL TEST (Slide)

Home > Product > WIDAL TEST (Slide)

The Widal Test Slide Kit is a professional-grade rapid slide agglutination assay designed for the qualitative detection and screening of specific antibodies against Salmonella typhi and Salmonella paratyphi in clinical patient samples. This diagnostic kit utilises the classic agglutination method to identify vital bacterial antigens (‘O’, ‘H’, ‘AH’, ‘BH’), making it an essential, high-utility test for rapid typhoid fever screening in modern laboratory environments.

Key Product Features

Accurate Slide Agglutination: Features optimized fluid antigens that yield distinct, crisp, and easily readable visual macro-agglutination clusters.
Comprehensive Antigen Profiling: Includes a full 4-antigen panel (O, H, AH, BH) for multi-strain diagnostic mapping of enteric fever variants.
Rapid Processing Turnaround: Designed for high-speed laboratory throughput, displaying clear results in under 2 minutes post-mixing.
Reliable Batch Consistency: Rigorously cross-checked parameters ensure highly reproducible and stable performance characteristics across multi-lot usage runs.

Frequently Asked Questions

Q1. What do the O, H, AH, and BH parameters mean in a Widal slide test?

Ans: These parameters represent specific antigens of typhoid-causing bacteria. The ‘O’ antigen refers to the somatic antigen of Salmonella typhi, while the ‘H’ antigen represents its flagellar component. The ‘AH’ and ‘BH’ antigens represent the flagellar components of Salmonella paratyphi A and B respectively. Measuring clump formations across these distinct blocks helps verify precise enteric infections.

Q2. What is considered a significant diagnostic titer baseline for a Widal test?

Ans: While local endemic parameters vary, a significant diagnostic titer baseline is generally identified when visible agglutination occurs at a titer greater than 1:80 for targeted antigens.

Q3. Why is serum preferred over whole blood for executing a Widal slide test?

Ans: This diagnostic assay relies on clean cross-linking between antigens and circulating antibodies. Human serum is the validated sample type because it contains concentrated antibodies without red blood cells, preventing visual interference during slide mixing runs.
