Very inaccurate, November 18, 2006
This review is from: CardioChek Portable Blood Test System (Health and Beauty)
I've used the CardioChek 6 times, and had my cholesterol checked at a doctor's office during the same period. My cholesterol levels according to the doctor's tests are always around 200. With the CardioChek they vary by as much as 90 points. It is a lot of trouble (and expensive) to purchase 3 sets of test strips and stab myself 3 times to test total Cholesterol, HDL Cholesterol, and Triglycerides. No test strips are included in the package when I purchased the CardioChek. The box says "includes check strips" but those are something other than test strips.

bad test strips, November 12, 2006
This review is from: CardioChek Portable Blood Test System (Health and Beauty)
I bought this product and the accuracy depends on having good test strips.
I simultaneously had bloodwork at the Doctor's office when I did the test.
Except for the total cholesterol, all the other tests were off. The manual states to check for the blue color at the back of the test strips after the test is done. Except for total cholestrol the other test strips did not have a blue color. The test strips which are expensive were bad. I am planning on returning this product

Great home testing device, May 2, 2008
This review is from: CardioChek Portable Blood Test System (Health and Beauty)
We have owned this device for many years and use it fairly regularly. My boyfriend doesn't like doctors, so it's good to have the CardioChek device for nearly instant home testing whenever we wish. It's great!
The device is about the size of a long pack of cigarettes and is SUPER easy to use. You can buy a variety of test strips for it. We have the total cholesterol, HDL cholesterol, and Triglycerides tests. From these, you can also calculate your LDL levels quite easily.
You turn on the CardioChek, slide in whichever strip you want to use, and then add in a drop of blood. We have an AutoLancet which is a one-button push pen-like item that easily gets a drop of blood without much pain at all. Then you wait maybe 30 seconds, and the device tells you the exact number.
We haven't had any problems with this system at all. If anything, the problem we have is that I don't bleed easily and my blood refuses to leave my body :) I find that running my hand or foot under warm water for a few minutes helps out. My toes seem to work better than my fingers, and are less sensitive, too.
Highly recommended, we haven't had any problems with this at all in the many years of use.
NOTE: There are multiple entries in Amazon for this device. Take a look at the other entry to see all the positive reviews for it. Yes you have to calculate the LDL value. I don't think a quick test *exists* for LDL. Plus, you always want to know all four numbers. Just knowing your LDL wouldn't be enough. You would would always want to do 3 out of the 4 tests, and then calculate the fourth, even if they DID have a LDL test. That way you can know all four numbers (which you do need to know) but only pay for 3 tests (to save some money).
As far as the test's accuracy, I can only guess that some people are doing this test right after they eat a gigantic meal full of sugars and fats. These tests *are* affected by what you eat! Do them first thing in the morning, after you've had a "natural fast" (i.e. sleep, unless you sleep-eat) and you'll be fine.
