Microbiological quality is a critical component of pharmaceutical product safety, regulatory compliance, and manufacturing control. Contamination can originate from raw materials, processing equipment, water systems, or manufacturing environments, creating potential risks to product quality and commercial distribution. Effective microbiological testing helps identify these risks, evaluate contamination concerns, and establish appropriate quality controls.
PD Partners provides pharmaceutical microbiology testing and analysis to support product development, quality control, and commercial manufacturing requirements. Our laboratory evaluates microbiological quality through scientifically established testing procedures and applicable compendial standards. By combining reliable testing with experienced scientific evaluation, we help clients identify potential microbial contamination, investigate quality concerns, and maintain confidence in their products.
How It Works
Microbiological testing begins with an evaluation of the product’s characteristics, intended use, and applicable microbiological specifications. PD Partners offers a range of compendial testing services to assess microbial quality, evaluate preservative effectiveness, and identify specified microorganisms.
Our capabilities include:
- USP <51> — Antimicrobial Effectiveness Testing: Evaluate the effectiveness of antimicrobial preservation systems in pharmaceutical formulations.
- USP <60> — Burkholderia cepacia Complex Testing: Evaluate nonsterile pharmaceutical products for the presence of Burkholderia cepacia complex organisms.
- USP <61> — Microbial Enumeration Tests: Determine microbial populations, including total aerobic microbial counts and combined yeast and mold counts.
- USP <62> — Tests for Specified Microorganisms: Evaluate pharmaceutical products for the presence or absence of specified microorganisms according to applicable compendial requirements.
Our laboratory also supports microbiological evaluation of raw materials, pharmaceutical water systems, manufacturing equipment, and finished products. Testing procedures are selected according to the product characteristics and applicable regulatory requirements.
