Advocates worldwide for change to MSM prohibitions point out that screening of donors should focus on sexual behaviour as well as safe sex practices since many MSM may always have protected sex, be monogamous, or be in other low risk categories. Some groups in favor of lifting the restrictions support a waiting period after the blood is donated when the donor is considered to have had behaviour considered higher risk, and before it is used, to match the blood bank's window of testing methods. While HIV is reliably detected in 10 to 14 days with RNA testing, older testing methods provide accuracy for only up to 98% of positive cases after three months.
