Overview

MDx BioAnalytical Laboratory, Inc. is a Texas-based analytical testing company founded in 2008. The site states its facility is located in College Station, Texas, and describes services including peptide purity, identity, and net-content analysis using HPLC-DAD coupled to a triple quadrupole mass spectrometer, along with sterility, endotoxin, and microbiological testing, stability studies, and elemental analysis. The site references an ISO/IEC 17025:2017 certificate from Perry Johnson Laboratory Accreditation, Inc., noting the certification is expired and pending re-accreditation following a March 2026 audit; a separate services page states ISO/IEC 17025:2017 accreditation is pending. The website lists leadership and staff, provides a certificate-of-analysis search tool, and offers a contact form for quote requests. Details are summarised from the company's own website and have not been independently audited.

Evaluation criteria

PAL Testing Evidence Score v1. How it works. – means not found in public sources as of 2026-09-30; it is not a finding that the facility lacks it.

Is this your facility?

Claiming is free. PAL first verifies that you are authorized to act for the business. Verified owners can then use three separate routes. Peptide Ad Lab never charges a business to correct a factual inaccuracy.

Company-provided updatesYour description, testing services, methods and instruments, facility locations, sample submission link, turnaround, pricing and contact details, shown in a section labelled “Provided by the company”. Not checked by PAL and not used in the score. Free: sent to PAL as correction requests. PAL Pro: published directly.
PAL-reviewed evidenceDocuments or links for a scoring criterion. PAL reviews them under the same rule used for every facility; only accepted evidence changes a finding. Any plan.
PAL-verified lab credentialsAccreditations such as ISO/IEC 17025. They count only after PAL finds them in the accreditor’s public directory. Any plan.

PAL Pro is an optional paid plan for company-provided updates, extra images and the PAL Pro badge. It never verifies a credential, accepts evidence, or changes a finding, score, eligibility or ranking position.

Ownership verification confirms that you control the business. It is separate from laboratory credentials and from PAL Pro, it is not an endorsement, and it does not change any finding or score.
