Partner offer
Need a drug screen for credentialing? The test usually is not specific to any one platform or hospital — one comprehensive panel can satisfy the requirement at nearly every facility. Our partner Accesa Labs offers a single chain-of-custody urine test that screens for 19 drugs, including fentanyl and other synthetic opioids, so one order covers you in almost every situation instead of a separate test per credentialing company.
