What time of month should I collect my sample?

Joseph Esposito -

Men can collect saliva at any time.

Woman need to collect based on the following list:

  • Do not have menstrual cycles can collect any day.  This would include women with hysterectomy, amenorrhea (abnormal absence of menses in women of reproductive age) and/or uterine/endometrial alblation (destruction of the uterine lining).

  • Have 'normal' menstrual cycles should collect day 19, 20 or 21 (counting the 1st day of bleeding as day 1)

  • Have irregular, unpredictable menstrual cycles can collect any day they are not bleeding.

  • Have some kind of cycle regularity but not at the typical lengths should follow these guidelines for collection: Long cycles – test at day 19-21 or from day 19 to 5 days prior to when the period is expected.  For example, if the cycle is 35 days, collection can be done anytime between day 19 to day 30. Short cycles – collection should be done a couple of days prior to when bleeding starts.  For example, someone with 14 day cycles should collect on day 12.
