Genuinely Helpful Health Check: Convenient Way to Test for Iron Issues
After months of feeling exhausted despite decent sleep and a supposedly healthy diet, I decided to check if anaemia might be the culprit before booking a GP appointment. This home test kit seemed like a sensible first step, and I'm glad I tried it. The kit arrived well-packaged with clear instructions and all the necessary bits - lancet for the finger prick, collection card, alcohol wipe, plaster, and prepaid return envelope. Everything was sealed and felt properly medical-grade. I was a bit nervous about the blood collection (not great with needles), but the lancet was surprisingly painless - just a quick click and hardly felt a thing. Getting enough blood onto the collection card took a bit of patience and hand-squeezing. Tip: run your hands under warm water first to get the blood flowing better! Posting the sample was faff-free with the prepaid envelope. Just make sure the blood spots are properly dried before sealing it up as instructed. Results came through via email within four days, which was quicker than the week they mentioned on their website. The report was comprehensive and easy to understand - showing my ferritin levels were indeed quite low (12 ng/mL when the normal range starts at 30), along with an explanation of what this meant and suggested next steps. Armed with these results, my GP appointment was much more productive. Instead of starting from scratch with tests, we could immediately discuss supplementation options. My doctor actually seemed impressed with the accuracy of the home test when compared with previous lab work I'd had done. At around £25, it's not cheap, but considering the convenience of doing it at home and the speed of results, I think it's worth it. Certainly cheaper than going private for blood tests. For anyone constantly tired, experiencing hair loss, or having other potential anaemia symptoms, this test provides a good first check before troubling the NHS. For me, it's led to proper iron supplementation that's gradually helping my energy levels. Only minor complaint is that the lancet is one-use only, and I needed a second attempt to get enough blood, so had to use one from an old diabetes testing kit I had lying around.

Great
* IF IT COMES UP ANAEMIA PLEASE GO TO YOUR GP AS THE ONLY ACCURATE TEST WOULD BE A BLOOD TEST* I brought this as I showed signs and symptoms and it did come up anaemia. I went to my GP explain what my results showed and I even took a picture and I had to get bloods. It’s easy to use, quality is good. Worth the money if you want to self test first before going to your doctors

Works well
Quick and efficient - identified low iron level which was confirmed with a follow up blood test from the doctor

Anaemia test kit.
To be honest not that accurate. Drs blood test was better.

Very unhappy with test
Very disappointed. Easy enough to use and my result came up positive showing I was low iron. Naturally I was worried about this so I booked a proper blood test at the GP based off this test. My GP test came back normal, actually upper end of normal. Happy not to be anaemic obviously but not happy this test gave a false reading which led me to waste a lot of time at the GP. Plus the price of this test. It's been a waste of my time & money. Don't bother to buy it.

Simple and reliable
I had an odd feeling that my iron levels were low. Used this kit, which showed deficiency that was later confirmed by a proper test at the doctors. I kept using this for the next 3 months, just to keep an eye prior to re-testing at the doctors. When my latest proper blood test showed normal iron 3 months later, this little kit also confirmed it. I think, it’s very convenient, easy to use, pretty accurate as a quick monitoring tool, and inexpensive. Of course, it won’t replace a consultation with a doctor and a proper blood test, but it’s a great starting point.

You might struggle with blood collection
I found this quite fiddly. My first finger prick on my ring finger dribbled blood and despite massaging the finger it dried up long before the dropper was at the full mark. It requires a fair bit of blood. So I used the second lance on my middle finger and it spewed blood. I thought "great that'll fill it!" But the capillary would no longer draw it in, presumably the blood already in there had started to dry up because it was taking so long. I ended up squirting out what was in there and trying it with it empty, which started to work just as my vision went and I had to sit down. I think I ended up with 2/3 or 3/4 the amount required, and temporarily blind and deaf with a cold sweat and it took a while to recover from it. I ran the test anyway and got a very, very faint band, so probably somewhere in the lower end of normal anyway. If I was going to try an at home kit again I'd get one with more than one capillary dropper in it and do it somewhere where I can quickly lie down! I'm not squeamish, I have a job that occasionally involves working with blood samples, but evidently when it's my blood, it's a problem! I think I'll probably stick to letting a doctor or nurse with a needle do the testing... Pros: Didn't hurt my finger at all, easy to use apart from the blood collection. Cons: I'm not cut out for blood collection, needs more spare parts in case of failed attempts, it's a shame for a whole kit to be wasted because there's not an extra pipette!

Seems OK. Results could be explained better.
Seems OK. Instructions could be better. So hope this helps: Reading Your Ferritin Rapid Test Normal Result: Two lines appear (T & C). Even if the 'T' line is faint, it's generally considered a normal reading, suggesting sufficient iron stores (ferritin > 30 ng/mL). Abnormal (Low) Result: Only one line appears (C). This means ferritin is low (< 30 ng/mL), indicating a potential iron deficiency. Consult your doctor. Invalid Result: No line appears, or only a 'T' line shows. The test didn't work. Repeat with a new kit. What to Do Next Faint 'T' Line (Normal): While this suggests normal levels, persistent symptoms like fatigue or pale skin warrant a discussion with your doctor, as rapid tests are screening tools. Single 'C' Line (Abnormal): See your doctor to confirm the deficiency and discuss treatment, which could involve supplements or addressing underlying causes like heavy periods or poor absorption. Invalid Test: Repeat the test carefully following instructions, ensuring correct blood volume and timing.
