has anyone used the CLEARBLUE DIGITAL PREGNANCY TEST????

Question

well i did the test and it said on the digital part NOT PREGNANT!! but when i took the strip out it had TWO LINES on it one strong line and one FAINT line but it was dark enough to be able to be seen what does that mean!! could i still be pregnant but the line is so faint that the digital part didnt pick it up?? has anyone had the same problem???

Answer 1

My digital test said "Not Pregnant," but the test stick has 2 lines. Am I really pregnant? The lines on the digital test stick (both Clearblue Easy Digital and e.p.t. Certainty) do not mean anything. They cannot be read like a regular test. The digital test sticks detect both hCG (pregnancy hormone) and LH (which "surges" around ovulation, but is present in some quantity nearly all the time.) Therefore, most women will have 2 lines on a digital test stick, even those who are not pregnant. See Secret of the Digital for an in-depth look at the digital test.

In simple terms, the digital test stick sucks up urine like a "regular" HPT. The test has a control line like every other HPT, to indicate the test worked properly. Then there is a "results zone" where a second line may or may not appear. Here's the difference: the second line may appear even if you are not pregnant, because the antibodies in the "results zone" are NOT testing ONLY for pregnancy hormone. Drumroll please. The "results zone" detects not only hCG (pregnancy hormone) . . . but also LH (luteinizing hormone.) LH is found in women's bodies almost all the time in some quantitity. (See the Fertility Info section for the nitty-gritty.) So, depending upon where you are in your cycle, how much LH your body produces normally (which can be thrown off by conditions like PCOS), you may see a second line even when there is no hCG ("Not Pregnant.")

Next question: Why does this HPT detect LH as well as hCG? After all, the presence of LH (or lack thereof) has no bearing on pregnancy detection.

Well, the best I can do there is quote the patent itself: "The determination of the presence of more than two (is multiple) [sic] analytes in any sample may have significant clinical utility." (Then it cites some examples in tests for heart disease and diabetes.) It does not elaborate further on the hCG/LH connection . . . so, in light of the fact that Clearblue just came out with a (disposable) digital ovulation predictor kit, my guess is the technology is the same in both tests and the company can use interchangeable parts and have the same patent cover both products.

Last question: How does the digital reader know what the result is? Here's the patent again: "... a standard curve can be generated by running strips with samples with known concentrations of E-3-G BI [the antibody "cocktail" with the dye/antibodies that detect the hCG and LH]. The colour at the immobile zone can be read, for example using a Minolta chromameter, and the concentration of E-3-G calculated by extrapolating from the reflectance value." In other words, your pee reacts with the reagents, makes a line (or doesn't), and the digital holder reads the specific intensity/color of the line, NOT SIMPLY determining whether a second line exists. (A "chromameter" just measures the shades of various colors-- so when teeth-whitening products say they'll lighten your teeth "at least two shades," they're basing those measurements of shades on a chromameter's reading.)

To recap: most women will normally see 2 lines on the Clearblue Digital test, pregnant or not, simply because of the normal, average, boring presence of LH. Our naked eyes cannot determine the "shade" or "intensity" of the second line, meaning our naked eyes can't make heads or tails out of the result. When the display says "Not Pregnant," believe it, until proven otherwise. (Note: Clearblue publishes the sensitivity of the digital test at 50 mIU/mL, but when questioned on their 800 line, they say 25. e.p.t. Certainty publishes their sensitivity as 50 mIU/mL as well. See the HPT FAQ for more info on why different tests work at different times-- and also why it is possible to receive a negative result and still be pregnant.)

Answer 2

No I don't suppose you're or was once pregnant. Missing a interval is one predominant signal of being pregnant and its very very infrequent for females to keep to have a ' interval like' bleed throughout being pregnant, now not unattainable however infrequent. Bleeding after the morning after capsule is common, it will probably make you interval a little bit later than ordinary for a cycle or 2 as good however this does not occur to all females. I could advise getting a well kind of birth control to preclude having to take the morning after capsule once more as its relatively now not very well to take them a couple of occasions. Good success :)

Answer 3

I don't use digital for that reason. Go get a regular one and see what you get. I know the regular ones say any faint line means you can be. If you really want to know for sure. Go to your doc and get a blood test done.

Answer 4

No I don't feel you might be or was pregnant. Missing a period is one foremost sign of being pregnant and its very very infrequent for ladies to proceed to have a ' interval like' bleed throughout being pregnant, no longer inconceivable but infrequent. Bleeding after the morning after capsule is traditional, it may well make you interval a bit later than usual for a cycle or two as good however this doesn't occur to all ladies. I'd propose getting a just right type of contraception to avoid having to take the morning after pill once more as its particularly not superb to take them a few times. Just right success :)

Answer 5

This happened to me......Yea I was preg!!! For me the faint line was cause I was only between 2-3weeks. I conformed it at 4 weeks at the DR. But you never know!!! Good Luck!!

Answer 6

i tried those tests but they always said not pregnant!! but my boobs had been sore for almost two weeks so i ordered some from babyhopes.com and it came back positive!!! and they were cheaper too!!

Answer 7

I did and it turned out negative every time.
