Make sure it's an iFOBT though ("immunochemical"), not the legacy gFOBT type. Preferably with two test fields - Hb and Hb/Hp (hemoglobin and hemoglobin/haptoglobin complex) - for that extra bit of sensitivity: https://europepmc.org/articles/PMC4927976/table/tab3/ https://europepmc.org/articles/PMC4927976/table/tab3/ Just buying a couple of those tests (they're cheap!) instead of going through the gatekeepers makes it practical to repeat them over the course of a few days, increasing the chance to catch intermittent bleeding. Obviously go to a doctor if there's any positive result at all.
