Can menstruation affect the results of a thyroid blood test?
Should you wait until your period is over before having a blood test to check your thyroid health?
“The research that has been done to date does not find a change in the levels when done with or without a menstrual cycle,” says Marcelle Pick, MSN, OB/GYN, NP, in private practice and co-founder of Women to Women Health Center, and author of the book, “Is It Me or My Hormones?”
Even if you’re cramping, bloated and feel miserable during your period or have a bad case of PMS, feel free to have your blood drawn for a thyroid test if that has been already scheduled.
Just make sure that you’re plenty hydrated so that it’s easier for the technician to “find” a vein from which to draw the blood.
