I put the blood drop at the tip, sides & all over the testing area; it still displayed E-2. Tried 6 times with varying amounts of blood. Whats wrong?

You have to wait until the drop appears on the meter, then add the blood to the tip. It only takes a very small amount of blood.

Reason : Sample Not Detected or Using Wrong Test Strip. Action : Retest with new or correct Strip and larger sample.

Did you try a new strip after you got the error message? The strips don't require much, but they do require some degree of accuracy, and they do not give second chances.If you tried a new strip, allowing the strip to wick the blood up into the testing area, and still got an error, you might need to recalibrate the tester.

The second line showing means positive however I kept mines after the test and it still showed one line only even after a month so you might wanna check further with a doctor ,not trying to scare you just might be best to ease your mind by checking with one .

Sorry but I am not a doctor and therefore would not feel confident in providing you a accurate answer. I can tell you though that the test did work exactly how it promised to. So take that for what it's worth. Hope that helps.

It shouldn't jump that erratic, clime & decrease in increments, seal it in a clear plastic bag an watch it to see if your readings steady & level off ? Might get your answer

Sorry cannot help - I tried using it a couple of times - almost impossible to hold to chest & get a reading. Just filed it in the closed & got a real good one. Microfife model 3AC1-PCCOS - Love it & check it after Dr appt - Very accurate!

Get the Wright's blood stain solution sold on here, and learn to prepare the slide properly. This allows differential staining for CBC. Do it for enjoyment and interest, though, and leave the interpretation of results to a clinician. You know what happens to people who start searching symptoms online....They either do not sleep well afterward, or end up with a mailbox full of Miracle Cures for things they never had. It's well known, and called "Intern Syndrome". Whatever the person last studied, they seem to develop the symptoms. Just human nature. I remember the first time I prepared a blood sample and looked at it. There were little things smaller than red cells jiggling around. I panicked and was certain I was loaded with some parasite, or dread plague. It was PLATELETS, being pushed around by Brownian Motion. They belonged there.

My EC-155 is having the same trouble. Did you ever figure out what was wrong?

I use one lancet to draw a blood drop big enough to supply enough blood to run the ketone test and the glucose test as well. You may, or may not, run both tests depending on what information you're looking for. Certainly you always throw out the lancet after its use. Not to say you can't use it to do a second prick right then, like if the first one didn't get enough blood or something. Just don't use the same lancet again later. Take it out and throw it away. That's why there are so many in the box. They're definitely a disposable item to prevent infection from a needle with old decaying blood on it.

I have done repeated measurements at the same time on the same drop of blood, several times. The measurement error seems to be about 5%, e.g. I might get readings of 95 and 100 from the same drop of blood using two different test strips (as you can't reuse the strips). How accurate it is, I don't know--I need to buy the control to assess that.

your ph could be off or your alkalinity.if the ph is out of wack it will give you bad readings thru out.i thing it would be a good idea to take a water sample to your nearest pool store and have them check your sample, between the shock and pool first aid my water was clear in a mater of hours and my pool was green when i took the cover off this year, good luck.

Try again in the morning when you first wake up. The urine will be stronger. I also believe it's more common to receive a false negative than a false positive. Good luck.

for ovulation they must be the same color or the test line must be darker. I always have 2 lines to, but a positive was obvious when I finally got one :)

Try putting your needle position on zero one. That should solve the problem.

Someone already mentioned this: try not to move when the machine is taking a reading, that the arm is supported on a table and the cuff is level with the heart. Make sure the arrow on the cuff is properly aligned and the cuff is tightened correctly. On occasion I receive errors, when I repeat, paying attention to the above suggestions, I get a reading.

it's still positive, maybe not enough urine was used...you can use another strip just to be sure, but it has been my experience that a faint 2nd line means positive

Yes, it does matter. If you look at the test strip, each end is different. One end is to take blood and the other is what attaches to the hand held machine. When you look at the strip there is a plain side and a side that is printed on (test side). On the end where you take the blood, there are 2 half moon black wicking areas where you take the blood & it wicks it into those areas.....hard to see the blood on the test strip, but if the droplet of blood is gone off the paw, it has been wicked up. Once you have collected a small amount of blood, you can insert the other end with the print side up into the machine. Hope that helps. Yes, it does matter.
