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.

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.

False result
Easy to use, gave a definitive result which said I was aneamic. So went to the GP who did a blood test the same day and I am definitely not anaemic. So inaccurate and not trustworthy. Waste of time and money, and potentially dangerous.

Did what it’s meant to do even tho GP ignored it. Easy to use.

Good for price, results can be tricky to interpret
I’m always a little dubious about these tests, but this one was really helpful for me so I feel I should review. I had been feeling quite tired so bought this on a bit of a whim. Test instructions were easy enough to follow, though the results are a bit tricky to understand. Two lines is normal, just one indicates deficiency - I had a very faint second line. Not sure what that meant, I decided to try taking some iron supplementation and retake this test a month later…again, showed a very faint second line, almost less visible than the first time, so I decided to follow up with a full blood test with my GP who confirmed that I am indeed iron deficient. Have since started stronger supplementation on their advice and feeling quite a bit better. This test is not perfect but for the price and ease I found it very helpful in giving me some indication of what might be causing my symptoms.

Has always been accurate for me!
Purchased on a couple of occasions as I was feeling unwell, and it has shown low iron, booked in at the doctors and on both occasions my iron was low so had to go on a course of iron tablets. Handy to use so you can check iron levels before booking in with Dr.

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!

Easy to use and possibly accurate
I bought this test to do a quick home check because I’m on a vegetarian diet and was experiencing fatigue. The test had clear instructions and was easy to use. This photo shows how my results came out after 5 minutes. I thought I could just about barely see a line, but I wasn’t sure if it was just a shadow. I went and had a proper ferritin test done at my GP, and that one came back as 30 ug/L which is on the edge of being low iron - so to me this test kit was possibly accurate. I would expect a borderline low result to leave you questioning like this. If yours comes out the same I’d advise a proper ferritin blood test with your doctor.

Eisentest fürs Blut
Sehr schnelle Lieferung. Werde es noch ausprobieren, sieht aber aus wie alle anderen. Somit bin ich noch nicht ganz aussagekräftig.

Zwei Tests, zwei unterschiedliche Werte.
Es ist leider nicht zu gebrauchen. Der erste Test den ich gemacht habe, sagt, dass der Wert zu niedrig ist und beim zweiten Test sagt der Wert, dass es ok ist. Also nicht wirklich brauchbar.
