Health Canada says all lots of Instant Aid pregnancy and ovulation tests are unauthorized. Learn how to identify affected products and what to do next.

Health Canada says all lots of the Instant Aid Ovulation Tester and Instant Aid Pregnancy Test are affected by a health product recall because the devices are unauthorized. The notice was published on October 26, 2026, and identifies Tj Trading Co. Inc. doing business as Three Star Industries as the company associated with the products.
This is not a recall limited to one expiry date, package size, or lot number. Health Canada’s listing names all lots of both products, so checking the lot number will not clear an Instant Aid test for use.
The regulator describes the issue as an unlicensed device for both the pregnancy test and ovulation test. That matters because home-use medical test kits must meet Canadian regulatory requirements before they can legally be sold in Canada.

| Product | Lot or serial number | Model or catalogue information |
|---|---|---|
| Instant Aid Ovulation Tester | All lots | INSTANT AID OVULATION TESTER |
| Instant Aid Pregnancy Test | All lots | INSTANT AID PREGNANCY |
Health Canada’s notice lists the recall as a Type II health product recall. The page shows a recall date of June 27, 2025, while the public alert itself was published and last updated on October 26, 2026. If you bought either product recently, treat it as affected regardless of when or where you purchased it in Canada.
“Unauthorized” does not necessarily mean Health Canada has confirmed that every test produced a false result. It means the product was not licensed or otherwise authorized for sale in Canada as required for this type of medical device. Health Canada warns that unlicensed home test kits may not meet Canadian standards for safety, effectiveness, quality, labelling, or oversight.
That creates a practical problem: a negative pregnancy result could provide false reassurance, while an ovulation result could be misleading when timing intercourse or making fertility-treatment decisions. The recall notice does not publish a product-specific accuracy rate or identify a particular defective component, so it would be inappropriate to assume that a past result was correct simply because it looked clear.
Health Canada also generally cautions that home tests are not a replacement for professional healthcare. Even licensed tests can produce incorrect results if they are used too early, stored improperly, read outside the instructed time window, or interpreted incorrectly.
If you have an Instant Aid Ovulation Tester or Instant Aid Pregnancy Test, the safest practical approach is to stop using any remaining units and avoid relying on previous results for important health decisions.

Do not flush test strips or liquid components. Unless the manufacturer, retailer, or local waste authority gives different instructions, place unused household test components in regular household garbage after making them unusable, and keep them away from children and pets.
Choose a home test sold through a reputable Canadian pharmacy, clinic, or established retailer, and look for Canadian regulatory information on the packaging. Health Canada says medical test kits for home use are medical devices and must be licensed before companies can sell them in Canada.
For a pregnancy test, follow the package timing instructions closely. A negative result taken too early may not rule out pregnancy, because hormone levels can still be too low for the test to detect. If you still suspect pregnancy, repeat testing after several days or contact a healthcare professional.
For ovulation testing, remember that an ovulation test is an aid for identifying an LH surge; it does not diagnose infertility or guarantee that ovulation will occur. If cycles are very irregular, fertility treatment is involved, or pregnancy has not occurred after the timeframe recommended by a clinician, professional advice is more useful than repeatedly changing test brands.

Read Health Canada's medical test kit guidanceThe Health Canada alert is a Canadian regulatory notice. It does not automatically establish the regulatory status of every Instant Aid product sold in the United States, and it should not be treated as a substitute for checking U.S. information.
If you purchased an Instant Aid test in the United States, keep your packaging and search the U.S. Food and Drug Administration’s medical device recall database by product and manufacturer. The FDA also advises consumers to use new home-test strips and devices that are authorized for sale in the United States.

Health Canada encourages consumers to report medical device problems, including concerns about unauthorized devices. Include the product name, lot information if available, where you bought it, when you used it, and what happened. Keep photographs of the packaging if you have them.
Report a medical device problem to Health Canada

A. No. The notice identifies the devices as unauthorized or unlicensed, but it does not provide a product-specific false-result rate. Because the devices were not authorized for sale in Canada, a previous result should not be treated as definitive when an important health decision depends on it.
A. Retest with an appropriately authorized pregnancy test and follow its timing instructions. If you still suspect pregnancy, the result conflicts with your symptoms or period, or you have urgent symptoms, contact a healthcare professional.
A. Health Canada’s public recall notice does not state a standard refund process. Keep your receipt or order details and contact the seller or the manufacturer listed in the notice to ask about return or refund options.
