Once we order the test and you have your blood drawn it takes anywhere from 1-3 weeks to get the results. The way this works, if you use us, is we do about a 10 minute phone consultation with you to establish your care with us. This may be done by one of our physicians or nurse practitioners. We then determine which Quest laboratory is most convenient for you and set up a time for you to go in for your blood draw. We then need to fax them some special instructions of this lab to be drawn and shipped. This process takes about two days to complete. You go in, make financial arrangements for the blood draw and test, your blood is drawn and shipped to the University of Washington, they run the test and get us the results. We then contact you with the results. If the test is easy to read, it takes about a week, if it is more complicated (which many low positive are), it can take up to three weeks. Most often the results are a clear negative or positive, but sometimes with these low positives we get an indeterminate result.
