Having a lab procedure performed can be intimidating. See below on how
to prepare and what to expect with each laboratory collection.
How to Prepare
Before your test, it’s important to know if you need to follow special
instructions before the collection process. Tell your doctor about any
medications you’re taking, including prescriptions and vitamins
or supplements. The way you prepare for a lab test depends on the type
of test. Ask your provider how to prepare and make sure to follow instructions.
For some tests, exercise, dehydration, eating and other activities can
affect your results.
What to Expect
Blood Collection - A phlebotomist will use a needle to take a sample of blood. In most cases,
the sample is taken from a vein in your arm. The phlebotomist will wrap
a rubber band or tourniquet around your arm, feel to locate a vein, and
insert the needle. You might feel a small prick or stinging sensation
when the needle is inserted. After the phlebotomist has obtained the correct
volume of blood, they will take the needle out and place a bandage. Press
firmly on the site to stop bleeding. Apply a cloth-covered ice pack to
your arm or hand if you have soreness or bruising at the puncture site.
Your sample will be routed to a lab for testing.
Urine Collection - A urine collection cup and cleansing wipe will be provided with instructions
on how to collect the sample. It is helpful to arrive to your appointment
with a partial or full bladder to ensure an adequate amount of urine is
able to be collected.
Test Results
Your test results will be shared with your provider. They can provide additional
consult and discuss treatment options or next steps in your care. For
most tests performed in our laboratories, results will be available within
24-48 hours after your specimen is received. Some specimens are sent to
an outside reference laboratory for testing. These tests may take up to
a week to receive results. Your lab results can be viewed in your online
MyChart Patient Portal.
