I ordered a vitamin D “home test” kit through Amazon. It was $40. D wasn’t part of the last couple of lab panels, for some reason.
The kit was from “Cerascreen.” They appear to be a German firm; at least you have to create a user account on a German web site to get your test results. The actual sample goes to New Jersey. The site worked with my not-common web browser and didn’t demand an excessive amount of information, though it did require my height and weight. It allowed selecting metric or US units. Weight came first, no problem. However, the back end couldn’t figure out any variants of feet and inches, so it thinks I’m five feet tall. I later realized the programmers were probably looking for a single integer, Euros thinking in millipedes or centipedes.
The test is basically just a few drops of blood into the sample container, but the instructions were complicated and in a tiny font in colors blending into a colored background. They instructions were clear, but annoyingly hard to read.
You’re supposed to run your hand under warm water for three minutes, then swing your arm around five to ten times, then use one of the two provided spring-loaded stabbies to puncture a finger, going in at a diagonal near the tip. Okay, for $40 I’ll follow the directions as-written. I test my blood sugar every day, but the stabby in the kit uses a wide blade instead of a needle. The sumbitch hurt. And then I could only get a couple of drops out. The instructions said four large drops were needed, and if there wasn’t enough blood the test would fail. After squeezing and cursing for a while I used the second stabby and still had to “milk” the finger, squeezing from the palm out. The sample holder is an interesting little device that looks sort of like a Roach Motel when you fold it up.
The kit came with a mailing bag and a prepaid mailing label with a barcode to identify the sample; I had to enter the human-readable alphanumeric onto the web page to link the sample with my account.
I expect to get the results sometime next week. It has been 36 hours and the bruise on my fingertip has gone away, but I still have two small scabs where the stabbies went in, and the finger is still sore. I didn’t realize how much work my right ring finger does on the keyboard.
I’ve put “ask for D3 test” on my list of things to ask for next time the doc runs a lab panel.
