Brown stain confirmed as blood with peroxide

26 February, 2008


I am 53, post-menopausal. I have not spotted since my last period, 4 years ago.

A couple of weeks ago, I noticed a brown stain on my (not white) underwear. Hydrogen peroxide confirmed that there was blood in it. I did this, since my first concern was the possible medical ramifications. (I am scheduled for a sono.) It stopped, but just started again: The spot was more than an inch in diameter.

What is my status?


Stains that are found on colored underwear do not render you niddah.  The fact that a stain is scientifically shown to contain blood does not change its halachic status.

You should continue to wear colored underwear and avoid looking at toilet paper to prevent becoming niddah from this staining. We also recommend abstaining from intercourse until the staining subsides.

You can review our article on Stains for further details.
