The enumeration test is actually a quantitative approach employed to find out the number of viable microorganisms present in the sample. This test is vital for making certain the microbiological high-quality of non-sterile products, which include pharmaceuticals, cosmetics, own care products, and health-related units.

The Microbial limit test (MLT) is executed to evaluate the quantity of and which of specified feasible microorganisms are existing in non-sterile pharmaceutical, Health care or cosmetics production samples that range from raw supplies to completed products.

In the drug microbiological limit test, it is achievable to know if the drug is contaminated and its degree of contamination, to learn the supply of the contamination, also to adopt correct techniques to Command it to be sure the caliber of the drug.
