Self-monitoring tests such as home pregnancy tests (HPTs) and ovulation predictor kits (OPKs) are widely available in local drugstores and pharmacies. However, the price of tests sold in stores is considerably inflated due to product resale turnover, transportation, and large overhead of the traditional retailing system supporting dozens of employees. Product marketing and packaging also raises the cost of tests sold in retail outlets.
The HPTs and OPKs that I sell are considerably cheaper because I don't operate with a lot of overhead, and the tests come with minimal packaging. However, despite their low price, you can rest assured that these tests are very sensitive and accurate.
The tests are bulk-packaged in original factory condition with no modifications, and they come with easy-to-use instructions. These products are made in Canada from US imported raw materials - hence being truly North American in origin! The shelf life of the tests is 2 years (an expiry date is stamped on each test), even though it has still shown great quality far beyond that. You are purchasing products with maximum expiry dates, rather than the products sitting in warehouses and aging on the retail shelves.
The test sold on this site are a no-name brand, and they possess 510k US FDA, Health Canada, Export Licenses, and Medical Device Licenses.
About OPKs
One Step LH Urine Ovulation Test is fast and easy-to-use. It is a qualitative test that predicts LH (Luteinizing Hormone) surge, and in turn, when you are likely to ovulate and conceive. Females who are trying to become pregnant may use this information to improve their chances of conception. Luteinizing Hormone is a hormone released by the pituitary gland, a small gland at the base of the brain. The hormone stimulates the ovaries to produce and release eggs each month during the menstrual cycle. The level of LH in the blood is highest before ovulation. This increase in hormone level is sometimes called a "surge". If fertility drugs are given to stimulate ovulation, an LH test can help determine the best time for sexual intercourse. The LH test may also be used to determine when eggs are mature enough to be surgically removed from the ovary as part of the in vitro fertilization process. LH tests may also aid in the diagnoses of polycystic ovary disease, premature ovarian failure, and menopause.
The tests detect LH in urine in a qualitative format with sensitivity of 25mIU/mL (International Standard Value) and specificity is 99.8%. Tests have an expiry date of 2 years and can be stored in a dry environment ranging from 2 to 30 degrees Celsius. Results are available in just minutes.

Instructions
- Bring the test pouch to room temperature (18-30°C). Collect urine into a clean container (such as plastic cup). The best way to collect sample is by placing a cup in the middle of urination process. To begin testing, open the sealed pouch by tearing along the notch. Remove the test from the pouch when you are ready to use it.
- Immerse the strip into the urine with the arrow end pointing towards the urine. Do not immerse past the MAX (maximum) line. Take the strip out after 5 seconds and lay the strip flat on a clean, dry, non-absorbent surface (e.g., mouth of the urine container). Do not immerse for longer than 7 seconds.
- Wait for colored bands to appear. Depending on the concentration of LH in the test specimen, positive results may be observed in as short as 40 seconds. However, to confirm negative results, the complete reaction time (10 minutes) is required. Do not read the results after 30 minutes as this type of test is designed for rapid determination only.
Interpreting the results
No LH Surge:
Only one color band appears on the control region or the test band is present but lighter in color intensity than the control band. There is no LH surge even if two lines present - as long as test line is fainter than the control line the result is negative.
LH Surge:
If two color bands are visible and the test band is equal to or darker than the control band, you will probably ovulate in the next 24-48 hours. If you want to get pregnant, the best time to have intercourse is after 24 hours but before 48 hours.
