How long does it usually take to get your blood test results back?

Question

Well basically i am having a blood test to see if i have had any vaccinations previously such as varicella and the measles mumps and rubella vaccine when i was younger since i dont know whether i am immune to it or not and if i am immune that means i do not need to have the vaccinations again.Just wondering the average time it takes to get the result back.

Answer 1

About a week. Some tests can take up to two.

Answer 2

Totally depends on what tests are being done.  Many are done within minutes.(hemoglobin, hematacrit, creatinine, pregnancy etc)  

Some take hours, (drug levels, clotting times, etc)

A few take longer, like a few days. (cultures, etc. )

Ask when they draw the labs or call the doctor office and ask.  If you are really anxious, they will sometimes give you an idea when they will be read.
