I bought ten and had one that was defective. I think they are "dime a dozen" tests so there are a few defective ones in the mix. It could be you just got unlucky. Also are you testing with urine that is extremely dilute? It may not be concentrated enough.

Invalid means the top line did not appears. That is very unusual. The most common explanation is inadvertent heat exposure, such as the test lying in direct sunlight for a lengthy period of time. The other possibility is the test was not held in the urine long enough to "pink up," that is begin to run. In that case, if it is just totally white, hold the test in the urine sample long enough to see it begin to turn pink. Then the test will run fully.

Hi,I'm not sure...I had 20 in mine when I received the tests. Good question!...

Hi, I know there is a special test fluid you can buy to check every bottle of test strips before you use them to make sure they are functioning properly, never had a box longer then about 3 months and never had a problem besides once in a while an individual strip giving an error message. Maybe you can contact the company/maker of the tests trips directly to make sure before you buy. Have a great day

I believe yes, there is. These are not a super high quality test so there is the possibility of false results. There are 10 in the box though, so you can have the tester take 2 at a time.

It takes about three days for the test and about a week to get the results back.

I don't know. I did the test twice. While they agreed I collected my sample , they claim they didn't get enough of my DNA. I have absolutely no idea what they have done with either of my samples. I really do not trust them. Take the test at your own risk, but realize you forfeit any rights and they can do whatever they want with your DNA samples.

From what I understand, these tests are NOT very accurate and I wouldn't get them again. But, the same thing happened to me last month when I had a chemical pregnancy. I would try a different test in another day.

My best guess is NO. If it's not the same number it's probably not the same strength reagent. If you have the brochure that came with the kit, it explains that there are different concentrations of reagents and different strengths will give inaccurate results.

I was getting all kinds of funky readings with mine before it fried. It was really the first time that I was checking a house of arc fault. Anyway after it burnt up i talked with tech support they don't have anything. And they told me that you can get many false readings. I won't be replacing it with the same thing

one was 7/14 and the other was 12/13 ... So no problems with that at all as I go through them kind of fast too. I test about 4 or 5 times a day.

No. Not likely. If you read the attaching documents it saids the results should be read within specified time. After minutes of the test the results will be compromised. In your case a month. We don't know what compounds from the environment in which u saved it has reacted to show two lines. And the chemical due ant have the active agent after that long. Read the documents. Or see a doctor if u have doubts

Test again. Any change in results after the test time are considered invalid.

I'm so sorry to hear that!! I didn't have any problems with false positives at all. Make sure you are not letting the sample go beyond the line and that you aren't keeping the test in the sample for too long. These can cause false positives. Also, certain hormone therapy drugs can cause false positives.

I used one for years and it worked fine. After that one failed, I tried buying new ones and never got a new one to work. I returned two and quit trying. I really like the results when the first one worked but after that I believe something in them fails and all the ones I purchased after that failed the same way. Same as your results.

Hi Alexandra-When you pull the test strip out of the package just dip it into the cup for 3 seconds. The stick should be turning a light purple color. If you have 2 lines it means its positive. If you have one line then it is negative. You said you had no lines so that means the test was inconclusive. I would try again. You might have gotten a bad stick. As for the cups, I just bought a pack of 100 cheap disposable cups for $15-$18. I hope this helps & if you have any other questions just let me know.

No worries! I forgot the second time too and I didn't see a difference in the results Margaret!!! :)
