Are there any risks to the test?
There are no known risks to having a sputum test, infant saliva test, or infant urine test.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
If you had a lumbar puncture, you may have pain or tenderness in your back when the needle is inserted. You may also get a headache after the procedure. The headache can last for several hours or up to a week or more.
If you had a biopsy, you may have a little bruising, bleeding, or soreness at the biopsy site. This usually goes away after a few days.
If you had an amniocentesis, you may have some mild discomfort and/or cramping during and/or after the procedure, but serious complications are rare. The procedure does have a slight risk (less than 1 percent) of causing a miscarriage.
