    What do I do if my off post doctor gives me a script to have blood work done?
    1. You may have your lab work done here at the IACH Lab. When you come in to have your labs drawn bring the script with you. We will enter all of the information into the computer and draw your blood.
    2. Once all of the testing is completed we will then fax the results to your doctor for you.

    How do I obtain a copy of my results?
    1. To pick up a hard copy of your results you need to go to Correspondence. Follow their processes and they will be able to print you your results. Correspondence is located across the hall from the lab in Corridor 4.
    2. It is your doctors' responsibility to give you your results. Give your doctor plenty of time to review your results before calling.
    3. We are unable to give you lab results because we cannot put your results into the context of your medical care.

    How long does it take to get results?
    1. We try to do most testing here in the lab. Tests that can be performed in house are usually completed within 24-48 hours. Tests that cannot be performed here are shipped to our reference laboratories and are usually completed within 7 to 10 business days. Please know that there are some exceptions to these time frames.

    What is fasting?
    1. Fasting means you do not eat or drink anything for a specified period of time.

    How long do I need to fast?
    1. Most tests require you to be fasting for at least 12 hours; some tests only require an overnight fast. Check with your doctor or call the laboratory for details.

    What can i have while I am fasting?
    1. While fasting you may drink only water and take any medication that does not require food. You may NOT have tobacco (smoking or chewing), chewing gum, breath mints and NO coffee or tea.
    2. If you take your tests and have not fasted the proper amount of time you may have to repeat the tests.

    What should I expect if my doctor has asked me to do a 1-hour glucose test?
    1. There are no fasting requirements for this test.
    2. You must be to the lab no later than 1530 (3:30pm) Monday through Friday.
    3. You will be given a glucose drink that must be consumed within 5 minutes.
    4. You may NOT leave the lab once you have started the test.
    5. You may NOT eat.
    6. You may NOT sleep.
    7. You MAY drink water.
    8. You MAY use the restroom.

    What should I expect if my doctor has asked me to do a 3-hour glucose test?
    1. You MUST be fasting for at least 12 hours.
    2. Expect to be in the lab for 4 hours.
    3. Arrive no later than 1200 (noon).
    4. You will be drawn 4 times.
      • First, we will draw your fasting sample. It will take 30 to 45 minutes for us to get results.
      • Once we receive the results then we will give you the glucose drink.
    5. You will have 5 minutes to consume the glucose drink.
    6. Once the glucose drink has been completed you will be drawn once every hour for the next 3 hours.
    7. You may NOT eat.
    8. You may NOT sleep.
    9. You may NOT leave the lab.
    10. You MAY drink water.
    11. You MAY use the restroom
    Why do you have to take so many tubes?
    1. With every patient, we try to draw as few tubes as possible. Unfortunately some tests require more blood than others or they require serum instead of whole blood. Tests that cannot be performed here require a separate tube to be drawn to be sent out.
    What do the different color tubes mean?
    1. There are two primary types of tubes used. One is a tube that contains an anticoagulant and prevents your blood from clotting (these are the light blue, lavender and pink top tubes), and the second are tubes that are designed to allow your blood to clot (these are the gold red and marble top tubes). Different test are performed on different components of your blood and that is why we have to pull different color tubes.
    Common Fasting Tests include:
    1. Lipid Panel
    2. Glucose fasting
    3. Insulin
    4. 3hr Glucose Tolerance Testing
    5. Vitamin B6
    Common Time Specific Tests:
    1. PTH-Parathyroid Hormone - Must be drawn before 0900 Monday through Friday
    2. CF-Cystic Fibrosis- Must be drawn before 1300 (1:00pm) Monday through Thursday
    3. Quantiferon- Must be drawn between 1100-1500 (11:00am-3:00pm) Monday through Thursday
    4. Factor V- Must be drawn before 1200 (12:00pm) Monday through Thursday
    There are several reasons why certain test need to be drawn at specific times.
    For example:

    1. Hormone levels peak at certain times of the day.
    2. Drug levels need to be monitored for high and low therapeutic levels.
    3. Thyroid hormone levels need to be collected at the same time (i.e. am or pm).
    Are you open on Federal Holidays?
    1. We are NOT open on federal holidays. We ARE open on training holidays with a reduced staff schedule.
      1. Training holiday hours are from 0700-1630 (7:00am-4:30pm).
