The Colusa Medical Center Laboratory is CLIA certified, offering testing in the specialties of chemistry, hematology, coagulation, transfusion and urinalysis. We provide services to both inpatients and outpatients, and accept physician referrals.

The laboratory is open for Outpatient services Monday through Friday from 7 am to 530 pm. No appointment required.

Preparing for your visit:

What to bring: A signed order, requisition or prescription from your doctor or healthcare provider; your photo ID; and your insurance card.

Glucose Tolerance Testing: Depending on the test ordered, you may be required to stay 1 to 4 hours. For your safety, you will need to stay near the lab for the entire testing period.

Glucose tolerance tests

Depending on the type of blood draw, this visit may take 1 to 4 hours. For your safety, you will need to stay near the lab for the entire testing period, as some people have a hypoglycemic reaction, causing nausea or light-headedness. If possible, it is best not to bring children to this visit, as it is lengthy, and child-appropriate activities may not be available. Call ahead of time before coming in for this test to discuss specific instructions and arrival time.
