These glucose test strips are used in lab experiments to measure rates of glucose diffusion by osmosis across semi-permeable membranes that mimic the small intestine; only $9.95 for 50 strips.
Although these strips can measure glucose accurately in urine, they should not be used to self diagnose medical conditions such as diabetes. Consult a physician if you have concerns.
We do offer a multipurpose test strip detects glucose in urine as well as proteins and ketones but it is intended for lab experiments in metabolism not self diagnosis. The other glucose strip is strictly for chefs to measure glucose in potatoes when preparing french fries.
One can show that starch does not cross the barrier but glucose does. The color test chart indicates concentration levels in mg/dL but you can convert this to mmol/L by multiplying by 0.055. eg. 100mg/dL is equal to 5.5mmol/L.
These strips are specific to glucose. You will not get a reaction with soft drinks or regular sugar since these are mainly fructose or sucrose. However, one simple demonstration anyone can do is to chew a saltine (salty cracker) and spit out a bit after a few seconds & test it. Then try it again but chew longer so that the salty taste disappears and begins to taste slightly sweet. The strips are sensitive enough to detect the glucose from the breakdown of starch.
These strips are not intended for medical diagnosis. Should you decide to test your urine & you get any positive result you should report it to your physician who can order a proper test for your blood sugar levels.
