What is STAT lab testing?

STAT lab testing is prioritized, urgent laboratory testing for time-sensitive clinical situations. MD Diagnostics dispatches mobile phlebotomists same-day to collect specimens at client facilities and delivers results rapidly — typically within 4 hours — once specimens arrive at the lab.

When should a facility request a STAT draw?

STAT testing is appropriate when immediate lab results are needed to guide treatment decisions, for new admissions requiring baseline labs right away, and to prevent unnecessary hospital transfers for long-term care residents.

How is STAT testing different from routine lab services?

STAT testing is prioritized for urgent situations and results are typically available within 4 hours, compared to routine lab services which deliver results within 24–48 hours. STAT orders also trigger same-day mobile phlebotomy dispatch to the client facility.

How long do results take?

Most results are available within 24–48 hours.

Do you confirm all presumptive positives?

Yes. Every presumptive positive is confirmed in-house to ensure accuracy.
