Your shortlist
Choose two or three laboratories above. Compare the scope for your sample, then confirm the details directly before sending it.
Ask for a current written quote that names the methods, sample requirements and report deliverables. Purity, identity and quantitative amount are different questions; compare the included scope before comparing the price.
Location alone does not establish whether a lab can test your sample. Confirm acceptance, shipping and handling requirements directly with the laboratory before sending anything. The region filter describes listed locations, not guaranteed service coverage.
Choose the questions you need answered. Copy the request and send it through the laboratory’s own contact channel. These fields stay in your browser and are not saved or sent to analytics.
This is a request for information, not a prescribed test panel. Confirm the lab accepts your sample before shipping or paying.
We review the provider’s published service information and link the source on each profile. We have not commissioned comparative tests or independently audited these laboratories. “Published services” means a source exists; it is not a quality score, accreditation check or endorsement.
We do not rank providers by an unsupported “trusted” badge. Prices, turnaround times, sample quantities and payment terms need a current quote from the lab. Check that any claimed accreditation covers the exact method you require.
