Blood Screenings at Covenant Health

For some blood tests, you will have to fast for a certain amount of time before the test. The fasting time may vary depending on the test. Inform your healthcare provider about any medications, supplements or herbs you are taking, as they can affect test results.

In most cases, a healthcare professional will use a needle to take a sample of blood from a vein in your arm. You might feel a small prick or stinging sensation. Once the provider has drawn enough blood, they will take the needle out and put an adhesive bandage over the site. The procedure typically takes only a few minutes.

Most people experience minimal discomfort and can quickly return to normal activities after a blood test. Some people develop a small bruise at the site where the needle was inserted, so it’s best to avoid heavy lifting with the affected arm for a day or two. It’s also important to eat a small, nutritious snack after the test to stabilize blood sugar levels, especially if you were fasting before the test.

Your blood sample will be sent to a lab where trained technicians will look for the information your healthcare provider has ordered. This may take a day or up to a week or more. Ask your healthcare provider’s office how you should expect to find out about the results.
