Recall records

No recall records for this company in the ingested FDA data.

Verification record

There is no verification record for this company. Most companies on this site have none: a record exists only where a company asked to be verified and MDM ran the checks, so the absence of one says nothing about the company.

Where there is a record, this is where it appears: what was checked, when it was checked, and the current status. An MDM Verified badge on another website links to a verify address on this domain that resolves to this section. A badge that does not resolve here is not ours.

Is this your company?

This page is built from public FDA records. Company pages are free and factual, and stay free whether or not anyone claims them. Membership never changes editorial coverage or vetting outcomes.

Claiming lets Radioassay Systems Laboratories, Inc. edit what it says about itself and list the categories it works in. It grants no badge: claiming is not verification.

The self-serve claim needs an FDA establishment registration, FEI or owner-operator number on the company’s record, and we hold none for Radioassay Systems Laboratories, Inc.. The only route for a company with no identifier on record is a person here: write to us, and one looks at the record and sends the same claim link by hand.
