Your Health Deserves Answers That Are Fast, Accurate, and Close to Home

Walk-ins are welcome during our business hours. However, if you'd prefer to minimize your wait time, you can call ahead to schedule a specific time slot. Some specialized tests may require a prior appointment.

Most tests require a physician's order or requisition form. If you don't have one, please contact your healthcare provider to obtain it before visiting. Some preventive screenings may be available without a referral — call us to ask.

Preparation varies by test. Some require fasting for 8–12 hours (water is fine), while others do not. Your doctor's order will include specific instructions, or you can call our lab at (313) 343-7700 to ask about your particular test.

Results are typically sent directly to your ordering healthcare provider within 24–48 hours for routine tests. You can also contact our lab to inquire about your results. We encourage you to discuss your results with your doctor for proper interpretation.
