Physicians order tests based on the signs and symptoms of your condition. It’s a good idea to ask your doctor during your office visit what tests are being ordered and the reason for them.
The volume depends on what tests are ordered. Most tests require 3-7 milliliters of blood (between a teaspoon and a tablespoon).
Not all tests require fasting. Your physician should provide you with instructions whether to fast before a blood draw.
We are required to verify patient information, ensure that a correct sample is collected and note if any additional testing is needed.
From the time you register, the process should take approximately 20 minutes. Some tests are timed, however, and may take longer.
Instructions for collecting stool samples are provided with the stool collection kits.
Results for routine tests are usually available within 24 hours. If your physician uses electronic medical records, the results are recorded as soon as technical staff can verify the results. Reports sent by courier arrive within 24 to 48 hours. If your physician receives mailed reports, allow 2-3 days, depending on where your physician is located.
The lab will not call you with your results. You will need to contact your physician’s office or access your test result via Providence MyChart.
Your physician can authorize that results be sent to you or another doctor, but the request must come from the physician who ordered the test.
Some test values change following the digestion of food. For example, if you eat lots of sugar, your blood sugar will be high. When you are fasting, we get a baseline result that can be compared over time.
Unless your physician tells you otherwise, continue to take your prescriptions. Ask your physician about over-the-counter medications.
You may drink only water. Do not drink juice, coffee, tea, diet soda or any other beverage regardless of whether or not it has cream and/or sugar in it..
Sorry, you may not eat anything while fasting.
No, not even sugarless. Gum stimulates your digestive system and can alter the test results.
No. Smoking can affect the test results.
No. Exercise can affect the test results.
Most people find it convenient to stop eating and drinking after 8 p.m. and to arrive at the laboratory early the next morning.
