Aquanox-16 Water Test StripsYou can't see lead, and you can't taste nitrate. Aquanox-16 reads 16 drinking water parameters at home in 30 seconds, against EPA-referenced guidelines.Each strip is individually foil-packed, so the last one reads as true as the first. Dip, wait 30 seconds, and match the pads to the reference chart. No lab equipment, no waiting.What it reads: 16 parameters including pH, total hardness...
Colonox FIT Stool TestTake control of your colon health with the Colonox FIT test, the same powerful tool healthcare providers use to screen for gastrointestinal disorders. This immunochemical fecal occult blood test (FOBT test kit) uses antibodies to detect hidden blood in your stool—a key indicator of issues like colitis, diverticulosis, hemorrhoids, polyps, or even early signs of colorectal cancer.

Send us a photo
Five blocks of pink on one small key, and bathroom lighting shifts all of them. If your pad sits between two bands, send a photo and someone on our team will match it with you.
Hold the strip flat against the colour key on the pouch so both are in the same shot.
Take the photo at 1 minute. After 2 minutes the pad keeps changing and the reading no longer counts.
Daylight if you can, phone straight above, no shadow across the strip.
How this works
Your photo is reviewed by a member of our support team. They are not healthcare professionals and cannot diagnose a condition or advise on treatment. What they can do is help you read what your test is showing.
Nothing here is automated. Your photo stays confidential and is used only to answer you.
Lost the card from your kit? You can still send a photo. Put the cassette on a plain white surface in good light.
Taking the test
Small handling details, and one that trips people up.
Reading time
Glucose is ready at 30 seconds. Leukocytes need the full two minutes. That 90-second spread is the thing people most often get wrong, and it's why a pad can look like it changed when it simply wasn't done.
In order down the strip, the way the chart prints them.
Nothing is readable after two minutes — whatever colour a pad picks up past that point has no diagnostic value, so a late read will tend to look worse than the result actually is.
pH and protein are the forgiving pair: they can be read at any point up to 60 seconds.

Questions
No. For a general check, read the whole strip once between 1 and 2 minutes — that's a qualitative read and it covers all ten. The individual times matter when you want the closest possible match on a specific pad, or when something came up positive and you're running it again. The table above has them in order.
That's expected. The strip is semi-quantitative, so the colour can land between two blocks — take the closest match. Foods, medications and vitamins can also produce a shade that isn't on the chart at all. If a pad looks unlike anything in its row, send us a photo rather than guessing.
Start by running the test again, reading that pad at its own time. These ten markers are designed to be read together — a single pad on its own is a piece of information, not a conclusion. If it repeats, take both results to a provider, who can put them next to your symptoms and history.
Worth waiting if you can. Blood is often found in the urine of anyone who is menstruating, and the leukocyte pad can read positive from vaginal discharge in the sample. Neither means something is wrong — it means the sample isn't clean enough to read those two pads fairly. Test a few days after.
It can. Large amounts of ascorbic acid can cause a false negative on bilirubin, and high concentrations can affect the glucose pad. Blood and nitrite are documented as holding up at the levels normally found in urine. If you supplement heavily and a result surprises you, mention it when you speak to a provider.
It screens for two of the signs. Leukocytes and nitrite together point toward infection and are worth a provider's attention, but nitrite can be negative even when there is one, because plenty of bacteria don't produce it. A strip result isn't a diagnosis, and it doesn't tell you what's causing anything.

Urinox-10 Urinalysis Test Strips
6, 20, 30, 60 and 100-test packs
Urinox-10 Urinalysis Reagent Strips are for in vitro diagnostic use and give qualitative and semi-quantitative readings for ten markers in urine. Results are intended to be used alongside other diagnostic information, not on their own, and this test does not diagnose any condition. False results are possible. Talk to your healthcare provider before making any decision based on a result.
