Procedure of tube agglutination test varies across kits. Kits designed exclusively for tube agglutination have different procedures.

In serial doubling dilutions, certain volume from the preceding tube is mixed and transferred to the subsequent tube. In doing so, the volume becomes more than preceding tube, therefore the volume received must be lost as well.

Excellent video, and well needed-Wikipedia dropped the ball where the Widal test is concerned. Question: Why was 1 millilitre discarded from the last tube?
