Contract Testing: Full Outsourced QC for Manufacturers
Outsource your quality control testing to Ayah Labs. White-label testing programs for contract manufacturers, private label brands, and supplement companies.
Ayah Labs provides contract testing services for manufacturers who need a qualified third-party laboratory to handle their QC testing program. We offer white-label testing, ongoing QC programs, and full outsourced testing for raw materials and finished goods.
Contract testing allows manufacturers to outsource their quality control laboratory work to a specialized third-party lab. Whether you are a contract manufacturer without in-house analytical capability, a private label brand that needs third-party verification, or a supplement company scaling up production, Ayah Labs provides the testing infrastructure you need without the capital investment of building your own laboratory.
What Contract Testing Includes
Our contract testing programs cover the full spectrum of QC testing requirements: incoming raw material testing, in-process testing, finished goods release testing, and stability testing. We work with your quality team to establish specifications, test methods, and acceptance criteria aligned with your product requirements and regulatory obligations. All testing is conducted under GMP-aligned protocols with full documentation.
White-Label Testing for Private Label Brands
Private label and white-label brands often need third-party testing to satisfy retailer requirements, Amazon compliance, or customer due diligence requests. Ayah Labs provides testing and CoA generation services that can be used directly with your brand name and product specifications. Our reports are formatted to meet retailer and distributor requirements.
Ongoing QC Programs
For manufacturers with regular production runs, we offer ongoing contract testing programs with dedicated account management, consistent turnaround times, and volume pricing. We can integrate with your ERP or quality management system to streamline sample submission and result delivery. Our scientists are available for technical consultation on out-of-specification results and quality investigations.

What is the difference between contract testing and in-house testing?
Contract testing means outsourcing your QC laboratory work to a specialized third-party lab like Ayah Labs. In-house testing requires capital investment in equipment, trained staff, and quality systems. Contract testing gives you access to validated methods, accredited infrastructure, and expert scientists without the overhead — ideal for growing brands and manufacturers without dedicated lab facilities.
Can you provide testing under our brand name?
Yes. We offer white-label testing where the Certificate of Analysis is formatted with your product and company information. This is commonly used by private label brands and contract manufacturers who need third-party documentation for their customers.
Do you offer volume pricing for ongoing testing programs?
Yes. We offer volume pricing and dedicated account management for manufacturers with regular testing needs. Contact us to discuss your production schedule and we will provide a custom pricing proposal.
