 Total Viable Counts (TVC)



 Absence of Specific Pathogens



Microbial Limits Test

ILS perform Microbial Limit Testing to the EP, BP, USP and the JP. The testing is used to estimate the total number of viable micro-organisms present and for the absence of specific pathogens in raw materials, exipients and finished products of all kinds.

The microbial limit (contamination) test is used to test the microbiological content of pharmaceutical products which are not designed to be sterile, or raw materials used in the production of other products.

The presence of micro-organisms within purified water can also be assessed at ILS by performing a Total Viable Count using membrane filtration.

Total Viable Counts (TVC)

Total Viable Counts is used to test for mandatory and non-mandatory guidelines on the quality of pharmaceutical preparations and medicinal products to ensure they comply with their microbiological specifications. ILS perform this testing to Pharmacopoeia standards or customers own methods.

Absence of Specific Pathogens

Testing for the absence of specific pathogens is to ensure the organisms below are not present in any pharmaceutical product or ingredient.

Staphylococcus Aureus
Pseudomonas Aeruginosa
Escherichia Coli
Gram Negative Bacteria
Candida Albicans
Clostridium Sporogenes


Various pharmaceutical preparations, depending on their use, require testing of various combinations of the above organisms.
