Human chorionic gonadotropin (hCG) is a hormone, produced by the formulating placenta shortly after the conception and secreted into the urine. The pregnancy test holds antibodies which distinctively react with this hormone. WHEN TO BEGIN TESTING The length of the menstrual cycle is the duration from your initial menstrual bleeding day to the day before the next bleeding begins. Determine the length of menstrual cycle before test. Please refer to the chart underneath to determine when you must begin testing. If your cycle is shorter than 21 days or longer than 38 days, consult a physician. If you do not know your cycle length, you may get started the test 11 days after your primary amount of time since the intermediate cycle length is 28 days. Perform 1 test each day over a 5 days period, or until the LH surge has been detected. PLEASE NOTE: LH tests cannot be frozen. Please make sure you have an indoor mailbox before placing the order in winter.

Great price Great product
By J. Divis
These are so easy to use and work really well. And to top it off they are so inexpensive! It makes it possible to test as often as you would like without it costing a serious amount of money. Every month that I used the LH surge strips I did get at least one day of a positive result and when we did finally get pregnant these were the first tests that I used and it was a clear result. The line showed up right away.
After having a miscarriage the doctor had me get several blood tests to track my hcg levels and make sure they were getting back to zero. I was curious to see if I would still get a positive on a pregnancy test so I used one of these tests the same day I had my blood drawn. The test showed up a faint line and I found out from the doctor the next day that my hcg level was 8 mIU/ml. (Which if I was actually pregnant would have been consistent with about three weeks pregnant.) So these strips are very sensitive and I’m very impressed with them.

WORKS! But you’ll want to do your research since no info comes with.
By Semper Fidelis
I bought these just to make sure that I was ovulating since my cycles are not predictable. I got pregnant in the first month of using them! Unfortunately I did miscarry but am now buying another months worth to try again.
The tests do not come with any information since they are simply medical supplies and they assume you know already. I did not know what I was doing for the first few days and after doing a lot of reading up on these tests I HIGHLY recommend going to [...] (peeonastick dot com)or google “How to use LH test strips” or something similar to learn all about testing your ovulation using these LH test strips. You do need to test twice a day and at certain hours of the day to be most effective. I personally set an alarm on my blackberry to test at 10 am and 10pm. You should test at the same two times every day for best results.
I almost always had two lines show but if the result line is not as dark as the test line it is negative. If just one part of the result line is as dark that IS a positive. The test line simply is showing you how dark it would be for a positive. You also should know that once you do get a positive result this does not mean you are ovulating. It is detecting your LH Surge which happens when an egg is mature and ready to ovulate in the next 48 hrs or so. I tested positive for about 34 hours.
PLEASE READ UP ON THIS SO YOU DONT WASTE YOUR STRIPS!

Awesome product, great price!
Great product! Even better price. I ordered these because we’ve been trying for a few months to conceive with no luck. I looked at OPK tests in stores and the tests run about $20 for 7 tests. I checked Amazon and found these for about $12 for 40 tests. I figured even if they don’t work, I’m only out a few bucks. I started testing in the morning about 10 days after the first day of my cycle. The directions advise to allow your urine to reach room temperature before testing. This was somewhat of an inconvenience, but I just left the urine in a dixie cup for about 30 minutes before I tested. The test is very obvious when negative and even more obvious when it tested positive. I tested positive after the 14 day of my cycle(I have a 27-30 day cyle). I would definitely recommend this product and I would no doubt reorder, but hopefully won’t have to. By the way, my order came only 4 days after I ordered them from this seller.
