3. Infection

Must not donate if:
a) Has active infection
b) Under investigation
c) On antibiotics to prevent urinary tract infection

If the donor has taken a single dose of an antibiotic after sexual intercourse to prevent urinary tract infection, is symptom-free on the day of donation, and does not have an underlying condition that prevents donation, accept.

Infection - General

Antibiotic Therapy

Donors may be taking prophylactic antibiotics long-term or as single post-coital doses. Anatomical anomalies within the urinary tract can make individuals more prone to recurrent infections. If a donor is accepted in accordance with the Discretionary guidance above, the importance of informing the relevant blood service of symptoms suggestive of urinary tract infection occurring within 14 days of donation must be emphasised with the donor. 

Donors on long-term antibiotics may have ongoing urinary tract infection without having any symptoms. As an active infection at the time of donation cannot be ruled out, these donors must not be accepted.
