What Is a Bioburden / Total Viable Count Test?

Bioburden (Biological Load) or Total Viable Count (Total Live Microorganism Count) is one of the fundamental microbiological analyses conducted to determine the live microorganism load present in a product, raw material, medical device, or production environment. These tests are of great importance in ensuring product safety, validating sterilization processes, and supporting quality control procedures.

In particular, determining the biological load for medical devices, pharmaceutical products, cosmetic products, biotechnological products, and various raw materials is recognized as a critical requirement under international standards and pharmacopoeias.

At NanoTox, we offer reliable and traceable Bioburden / Total Viable Count testing services within our Microbiology Unit, in full compliance with international standards.

Purpose of the Bioburden Test

The bioburden test aims to determine the total number of viable microorganisms present in a product or sample.

Through these studies:

• Product microbiological quality is assessed,
• Sterilization processes are validated,
• Production processes are monitored,
• Sources of contamination are identified,
• Regulatory and quality requirements are met.

The data obtained plays a crucial role in demonstrating that product safety and production processes are under control.

Why Is Bioburden Analysis Important?

Uncontrolled microbial contamination in production processes can negatively impact product quality and user safety. Therefore, the regular monitoring of bioburden is an essential component of quality management systems.

Bioburden analyses are widely used in:

• Prior to sterilization validation,
• In routine quality control studies,
• In production environment monitoring programs,
• And in product development processes.

Studies Conducted in Compliance with International Standards

Bioburden / Total Viable Count analyses conducted at NanoTox are performed in accordance with international standards and pharmacopeia requirements.

Key reference documents:

• ISO 11737-1:2018 – Determination of Microbial Populations in Medical Devices Intended for Sterilization
• European Pharmacopoeia (Ph. Eur.) 2.6.12 – Microbiological Examination of Non-Sterile Products: Microbial Enumeration Tests
• USP <61> – Microbiological Examination of Nonsterile Products: Microbial Enumeration Tests

Studies conducted in accordance with these standards ensure the attainment of reliable results recognized internationally.

Parameters Evaluated Within the Scope of Testing

Various microbiological parameters are evaluated depending on the sample type and the relevant standard:

• Total Aerobic Microbial Count (TAMC)
• Total Yeast and Mold Count (TYMC)
• Total Viable Microbial Load
• Product-specific microbiological quality assessments
• Pre-sterilization biological load analyses

These data provide comprehensive information regarding the product’s microbiological status.
