Widal Test

Whole cell agglutination test in which antibodies to salmonella(the cause of typhoid) are detected in the serum of an infected person

[@kevinbroderick3779]

Pro tip: Add the sample to the solution, not the solution to the sample. One slip of a dropper and you've contaminated it and it needs to be thoroughly clean before it's put back in the bottle. By placing your solutions out first, there's no possibility of contaminating the bottles.

Oh, sorry about that. Hope you’re on medications

[@hungryboy5452]

We use serum, y did u use plasma

[@eliassoumda1989]

the timing is not respected.

[@MMLV360]

Thank you for your observation and comment!🙂 The timing for rocking the tile ideally is 1min for +ve result(but 2mins just to be sure). Although i didn’t, rock it for exactly 1 minute(55 secs), I just wanted to demonstrate the procedure and the main concept in carrying out this test 👌😉

[@favourfave1185]

The first four are they typhi or paratyphi

[@MMLV360]

According the way they were arranged, the first 3 from the left are PARATYPHI, and the last one is TYPHI in each case.

[@ramaalsaresy8023]

in the slide number 7 there was bubble how we can avoid that ?

[@MMLV360]

Yes, you can avoid that by filling the pipette with the antigen sample you're taking. Thanks for the observation.
