When conflicting outcomes arise in just a test operate, corporations need to seek advice from USP Chapter , Gel Clot Limitations Test, Interpretation, for direction on repeat testing. As specified in Chapter , In case the test failure transpired at below the utmost valid dilution (MVD), the test needs to be recurring using a increased dilution not exceeding the MVD. A history of the failure really should be A part of the laboratory results.
If a clot has formed and remains intact at the bottom in the tube, the result of the test is favourable, exhibiting the concentration of endotoxin in Remedy is equivalent to or increased than the sensitivity of lysate utilized.
