Kidney stones and blood donation

Yes, you can donate. Yes, once the stone has passed or been treated and you are pain-free, kidney stones do not stop donation. ## The short answer A settled stone changes nothing about blood safety or your fitness that day. Active colic (pain now), infection, or recent surgery waits until resolved. ## At the screening desk Tell the staff: Recent episodes and any medicines. That conversation is confidential and takes a minute, it exists so the medical officer can clear you safely on the day. Everyone meets the same basics: age 18,65, weight 50 kg+, haemoglobin on target, feeling well today. Men donate every 3 months, women every 4, the rest rules, simply. Not sure about your case? Try the Can I donate? checker or read who can donate and the deferral list in plain words. Still weighing it? Is blood donation safe? and the honest side-effects list are straight answers, not brochure talk. ## The one line that matters The medical officer at the centre makes the final call on the day, with your name, your file and your actual reading in front of them.
