Ketostix are available at most pharmacies such as Walgreen’s or Duane Reade, but I prefer to purchase Ketostix online, typically via Amazon.
I have found that Amazon’s prices are cheaper than my local pharmacy, and I love the convenience of having them shipped right to my door.
If a site has Certified Metrics instead of estimated, that means its owner has installed code allowing us to directly measure their traffic.
These metrics have a greater level of accuracy, no matter what the ranking.
The test relies on the dehydration reaction which occurs more quickly in ketoses, so that while aldoses react slowly, producing a light pink color, ketoses react more quickly and strongly to produce a dark red color.
Ketoses can isomerize to aldoses through the Lobry-de Bruyn-van Ekenstein transformation.
Not all websites implement our on-site analytics and publish the results.
For these sites, we show estimated metrics based on traffic patterns across the web as a whole.
We answer all that and more in our complete guide to Ketostix and ketone urinalysis testing.Estimates are more reliable the closer a site is to being ranked #1.Global traffic ranks of 100,000 are subject to large fluctuations and should be considered rough estimates.Certified Site Metrics are metrics that are directly-measured from the website instead of estimated.The website owner has installed an Alexa Certify Code on the pages of their site and chosen to show the metrics publicly.The simplest ketose is dihydroxyacetone, which has only three carbon atoms, and it is the only one with no optical activity.
