Frequently asked questions
What does a positive result mean?

How long does it take to get results?
Results are usually available within one to three business days after the sample reaches the laboratory. The exact time can vary depending on the lab's workload and other factors. Your ordering clinician will receive and discuss the results with you.
Is this test painful?
The test involves a standard blood draw, which may cause a brief pinch or sting when the needle goes in. Most people tolerate it well, and the discomfort is temporary. You can ask the collection staff about ways to make the process more comfortable.
Do I need to avoid any medications before the test?
Some medications, such as antihistamines, can affect allergy test results, but not all tests require you to stop them. Always check with the laboratory or your clinician before changing any medication routine. They will give you specific instructions based on the test method used.
