How to Choose the Right Laboratory Testing Panel for Your Product

Whether you're launching a new product or expanding an existing product line, selecting the right laboratory testing panel is an important part of building a strong quality assurance program.

Different products require different types of testing depending on their ingredients, manufacturing process, intended use, and quality objectives. Understanding the purpose of each testing panel helps manufacturers make informed decisions while supporting product quality and consumer confidence.

This guide explains the most common laboratory testing panels and how they help manufacturers evaluate products throughout the production process.

What Is a Laboratory Testing Panel?

A laboratory testing panel is a group of analytical tests performed on a product to evaluate specific characteristics or quality attributes.

Rather than ordering individual tests separately, manufacturers often select a panel that includes multiple analyses relevant to their product category.

The appropriate panel depends on the materials being tested, production methods, customer requirements, and internal quality assurance goals.

Common Types of Laboratory Testing Panels

Potency Testing

Potency testing measures naturally occurring compounds or active ingredients present within a product.

For hemp-derived products, potency analysis is commonly used to evaluate cannabinoid profiles and verify product consistency between production batches.

Heavy Metal Testing

Heavy metal testing evaluates products for elements such as:

• Lead

• Arsenic

• Cadmium

• Mercury

Routine testing helps manufacturers evaluate ingredient quality and support comprehensive quality assurance programs.

Microbial Testing

Microbial testing evaluates products for microorganisms that may affect product quality.

Depending on the product, testing may include evaluations for:

• Yeast and mold

• Salmonella

• Escherichia coli (E. coli)

• Total aerobic microbial count

Pesticide Testing

Pesticide testing evaluates products for residues that may be associated with agricultural production.

Routine screening provides manufacturers with valuable information about ingredient quality and production consistency.

Residual Solvent Testing

Residual solvent testing evaluates products manufactured using extraction or solvent-based processing methods.

This testing helps manufacturers verify product quality and evaluate extraction efficiency.

Water Activity & Moisture Testing

Water activity and moisture content can influence product stability and shelf life.

Routine testing helps manufacturers better understand storage characteristics and support product consistency.

Choosing the Right Testing Panel

Every product is different.

Factors to consider include:

Product Type

Different products often require different analytical approaches.

For example, botanical extracts, dietary supplements, functional beverages, cosmetics, and hemp-derived products each have unique testing needs.

Manufacturing Process

The production method often determines which analytical tests are appropriate.

Products manufactured using extraction methods may require different testing than products made through blending or encapsulation.

Raw Materials

Incoming ingredient quality can influence which testing panels provide the greatest value.

Manufacturers often evaluate raw materials before production begins.

Quality Assurance Goals

Some manufacturers perform routine testing on every production batch, while others develop customized testing schedules based on product type and production volume.

Selecting the right testing panel helps support long-term quality management.

Why Work With a Third-Party Laboratory?

Independent laboratories provide objective analytical data that manufacturers can use to evaluate products throughout the production process.

Third-party testing helps manufacturers:

• Verify product quality

• Monitor batch consistency

• Evaluate supplier performance

• Support quality assurance programs

• Build consumer confidence

• Strengthen manufacturing decisions

Reliable laboratory data also supports continuous improvement over time.
