menses but want to donate blood

[seankoh]

Hi,

My friend wants to donate blood tomorrow but these few days she has menses. I wish to know whether she can donate blood or not.

Thank you very much.

Better wait. Donating blood now can weaken her body. Furthermore, she may not pass the hemoglobin test now.
