Correct answer: A — Check Rhesus status and arrange anti-D if indicated

Check Rhesus status and arrange anti-D if indicated is the best answer because the vignette is testing Rhesus status in bleeding and the recommended approach is consistent with NICE NG126; BCSH guidance. The other tests may be useful in different pathways, but they would not be the most direct first investigation for this presentation. Specifically, Urine pregnancy test; Full blood count; High vaginal swab; 75 g oral glucose tolerance test would be suboptimal in this scenario. The first investigation should answer the immediate clinical question and follow the relevant UK pathway.
