Vitamin D Test (1 Test) | Rapid Test | at Home Test | Self Test

I strongly advise against purchasing this Vitamin D test. I bought two of these tests, hoping for a quick and easy way to check my Vitamin D levels at home. However, both tests indicated that I had very low, deficient levels of Vitamin D. Unsatisfied with the results, I went ahead and got a proper blood test done just a few days later, and to my surprise, my Vitamin D levels were actually 100, completely opposite to what these at-home tests showed.It’s clear that this product is not accurate, and I ended up wasting my money and it's not Amazon returnable. If you’re looking for reliable results, I would not recommend this test at all. Save yourself the hassle and invest in a proper blood test instead. You health is most important.

This product worked great for me. I used a magnifying glass and it helped a lot. I take 10,000 IUs of vitamin D three every day for years. I was right in the middle. Adequate levels.

I saw a similar product on YouTube available in England for about 6 pounds. It appears to be the same product or process. I'm a bit skeptical of the results as it is a bit difficult to read. Additionally, of the five tests I ordered one had the buffer bottle lid off which spilled in the bag. Because I bought 5 that was not a problem. For the cost I am not impressed.

After taking vitamin D for at least a year, I was curious about whether I was taking too much. This test is very good at ruling out excess vitamin D, but is less useful for determining sufficient or insufficient levels.The test shows a pale line for both, with only a slight difference in intensity to distinguish the two. I'm satisfied with my result as it answered my question, but I'm still not certain if my vitamin D level is adequate.

This test was terrible. I could not get the lancets to work. I had to prick my finger with a needle. Then the dropper would not work. I also expected a number, not a range. I did a at home test before and got a number A range of 30 to 10o is worthless since you need to be at 50 or better.

I already know what my D levels were a few months ago and wanted to test to see if there's been any improvement without having to go back for another lengthy office visit if it's not necessary. While the test doesn't provide exact blood values, it did provide a range. Anyway, I tested below "Sufficient" so I guess it's back to the doctor's to have my supplement dosage adjusted. For me personally, the test costs way less than my copay so it was worth finding out if I was still deficient. If you want exact blood values, you'll either need to see your doctor or order the home collection kit that has to be mailed in.

The color card is terrible. I don't know if the result is insufficient or sufficient. I guess from the box it should be sufficient.And don't be misleaded by the instruction. You need to squeeze the dropper a little to make it suck in some blood.

VERY WRONG result! I keep my D blood level at about 200 and this test showed mine to be 10 to 30!My daily D3 is 10,000 IU to maintain 200. And, I include vitamin K2, MK-7, to protect my arteries from any Calcium buildup.I want a refund for the bad test device!
