Clinical laboratories play a crucial role in health care. About 70% of today’s medical decisions depend on laboratory test results, according to the Centers for Disease Control and Prevention.

Enloe Medical Center offers a full scope of laboratory services and accepts physician referrals.

For your convenience, outpatient lab services are available at the Enloe Clinical Lab inside the hospital and at the Enloe Laboratory at Fountain Medical Plaza. Lab specimen collection for Enloe Women’s Services patients is also available in the Enloe Women’s Services Clinic at 1423 Magnolia Ave.

  • CBC (Complete Blood Count)
  • PT/INR (prothrombin time/ international normalized ratio)
  • PTT (partial thromboplastin time)
  • Basic and comprehensive metabolic chemistry panels
  • Glucose tolerance
  • Thyroid testing, including TSH and free thyroxine (free T4)
  • Semen testing for infertility, as well as post-vasectomy testing (by appointment exclusively at the Esplanade location)

Prepare for Your Visit

To prepare for your visit, please:

  • Bring an order, requisition, or prescription from your doctor or care provider; your photo ID; and your insurance card. We accept most insurance plans.
  • Wear a shirt that allows access to your arm, either short sleeves or sleeves that easily roll up.
  • Follow any other instructions your doctor has given you.

Fasting: May be required for certain tests. If you are required to fast, do not eat or drink anything except water before your lab test. You can continue taking your medication as prescribed. Fasting is generally 8 to 12 hours. However, follow your doctor’s orders.

Glucose tolerance tests: Depending on the type of tests that have been ordered, the appointment may take 1 to 4 hours. For your safety, you will need to stay near the lab for the entire testing period. Some people have a hypoglycemic reaction, causing nausea or light-headedness. If needed, make arrangements for child care.

Gestational glucose tolerance test: If you will be having this test, please read these Gestational Glucose Tolerance Test patient instructions.

Obtaining Your Lab Results

The majority of tests in Enloe’s labs are processed and reported within the same day. Tests involving cultures take longer to process. Some tests need to be sent to an outside lab, and results for these can take three to four days.

A copy of your lab results will always be sent to the doctor who ordered the tests. Your doctor will follow up with you about your results, and any questions you have should be discussed with your doctor.

Most labs results are also available in MyChart, with the exception of any that California law prohibits from being transmitted electronically and via the internet. If you do not have MyChart yet, sign up online.

For your convenience, you may request a copy of your lab results directly from the laboratory. You will need to complete an authorization form (autorización para el uso o revelación de información médica). If your family member or another person will be picking it up for you, you will need to sign the form and have it witnessed.

Billing & Insurance

Enloe Medical Center accepts most insurance. Cash pay with discount plans for the uninsured and payment plans are available. Patient Financial Services can be reached at 530-332-6300. Get more information on billing and insurance.
