Hi everyone, I'm unsure what haematocrit is on a FBC but it has come back very high or very low and I'm unsure what this means, I wondered if anyone can help interpret this for me? The rest of the results on the FBC look good but it's just this one... it says 0.37-0.47 is normal range and mine is 0.385 which to me looks a huge difference but again I'm not a doctor, I've been so unwell for a long time now so really want to know what this could mean? ( I have contacted doctors they said the full tests are not back yet so they won't view it yet until it is) online says it could be anemia or the horrid C word but again all of the FBC results are within range as I've checked, it is just this one strangely enough. Thanks!
