Q. What are the laboratory hours?
A. M - TH 8:00am - 4:30pm and Friday 8:00am to 3:00pm

Q. Do I need to call ahead for labwork?
A. Yes if you are not scheduled for a doctor's appointment at the same time. Please call at least one hour before you plan to be here so we can have your chart ready.

Q. Do I need to fast?
A. That depends. For lipid (cholesterol) testing, blood glucose (sugar), and 3-hour glucose tolerance tests, yes you must fast or be rescheduled. For 1-hour glucose screening and most other lab tests (i.e. thyroid, progesterone, etc.) fasting is not required.

Q. Do I need to schedule my lab tests?
A. Only if you need to do the 3-hour glucose tolerance test. All other tests may be done at your convenience within our laboratory hours. But don't forget to call ahead.

Q. Is your laboratory certified?
A. Yes it is! We are inspected and certified by CLIA - a laboratory oversight government agency. Both lab techs are also certified by nationally recognized organizations.

Q. Will I just get my finger poked or will the blood come out of my arm?
A. That depends. It will most likely be taken out of your arm. The 1-hour glucose screen is an example of when we just stick your finger.

Q. How do I collect a 24-hour urine?
A. 1. You will receive a special 2-quart, 24-hour urine container to use for the test.
2. Start the test on a day that you will be able to save all of your urine. You may want to do this on a day that you are at home. Many patients have found that they can do their collection at work also. It will depend on your comfort level. However all of your urine must be collected for 24 hours.
3. Begin by emptying your bladder in the toilet. DO NOT save this urine. Write the date and time on the 24-hour urine container.
4. The next time you urinate, save the specimen. Save all urine for the next 24 hours. Females may find it easier to urinate in a separate container and then pour the urine into the 24-hour urine container.
5. Exactly 24 hours after step #3, empty your bladder and save this urine in the 24-hour container. You are finished with the test.

Q. What are the instructions for the 3-hour glucose tolerance test?
A. You need to be fasting for 12 hours prior to your test. Nothing to eat, but you can drink all the water you want. It is okay to take your prenatal vitamins, and any other medications that can be taken without food. Start time is 8am sharp. Please tell the front desk that you are here for your 3-hour glucose test. We will call you back to the lab and draw your blood to check your fasting blood sugar first. Then we will give you a drink similar to the one you had with your glucose screen, only it has twice the glucose content, and it is lemon-lime flavored, not orange. Then we will drayw your blood and check your glucose at 1, 2 and 3 hours after you've had your drink. Bring a good book, crafts, or paperwork to do because you will be here for 3 hours. You need to stay in the building the entire time, and remember to wear a watch because you are responsible for watching the time and coming back to the lab when required. If you have questions, please call the lab at 288-3287 and if you need to reschedule, please let us know as soon as possible.

Q. What are the instructions for the 1-hour glucose screen?
A. This test involves drinking a glass of sugar solution and having a blood sample taken from your finger an hour afterward. If you know you are having a glucose screen at your next appointment, please do not smoke for about six hours before coming in. You do not need to fast for this test, please eat as you normally would. Give your Glucose Screen card to the receptionist when you arrive and a nurse will bring you the sugar solution before your appointment. If the test is normal, there will be no further testing. If the result reveals a high blood sugar, you will be scheduled for further testing.

LAB - It is important that you verify with your insurance company before your visit or if your insurance changes where your labs are to be sent. You will be responsible for any lab charges that were sent out of network.
