What is USP 61 microbial limits testing?

USP <61> is often called a “Bioburden” or “Microbial Limits” test. This test determines how many microorganisms are present in non-sterile drug products. During a USP <61> test, a sample is prepared and plated on two types of growth media (Soybean-Casein Digest Agar and Sabouraud Dextrose Agar).

What is MLT test?

The microbial limits test (MLT) procedures described in USP <61> and <62> are performed to determine whether a product complies with compendial specifications for microbial quality, and consists of two parts. The qualitative phase of a microbial limits test is known as the Test for Specified Microorganisms.

What is MLT in pharmaceutical?

The microbial limit test (MLT) is performed to assess how many and which of certain viable microorganisms are present in non-sterile pharmaceutical, healthcare or cosmetics manufacturing samples that range from raw materials to finished products.

What is MLT in pharmaceutical industry?

Process of the analysis of the Pharmaceutical samples for Microbial Limit Test including yeast & molds and pathogens like E. coli, Salmonella, Pseudomonas aeruginosa and Staphylococcus aureus.

What is the difference between USP 61 and 62?

USP <61> testing includes an enumeration plate count and suitability testing, which validates the plate count. USP 62 testing evaluates the presence or absence of specific organisms.

What is TAMC and TYMC?

aMinimum amount of product to be used in sample preparation; cfu = colony-forming unit; TAMC = total aerobic microbial count; TyMC = total combined yeasts and molds count. criteria for evaluation of product quality: 1.

What is a sterility test?

What is sterility testing? Sterility testing is designed to demonstrate the presence or absence of extraneous viable contaminating microorganisms in biological parenterals designed for human use. The sterility assay is 14 days allowing for an appropriate incubation period to detect slower-growing microorganisms.

What is SGPT test?

SGPT means Serum Glutamic Pyruvic Transaminase. This test is done to measure the amount of Glutamate Pyruvate Transaminase (GPT) in blood serum. GPT is an enzyme found in heart cells, kidney, muscles and liver. An SGPT test is needed on a regular basis to keep the liver in a healthy state.

What is TVC in microbiology?

Determination of the total viable count (TVC) in a food product is one of the simplest and widely used microbiological techniques. TVC typically is conducted to obtain information about the microbiological quality of foods.
