A second type of food testing strip is a gram-negative swab, which is usually administered directly to the food itself. Gram-negative swabs generally work faster than enzyme reactant strips, but they differ in that the gram-negative swabs are designed to detect a broad group of organisms, not just those that can cause foodborne illness in humans.

People with type 1 diabetes usually have a wider range of glucose levels, and glucose peaks above normal, often ranging from 40 to 500 mg/dL (2.2 to 28 mmol/L), and when a meter reading of 50 or 70 (2.8 or 3.9 mmol/L) is accompanied by their usual hypoglycemic symptoms, there is little uncertainty about the reading representing a "true positive ...
Sample sizes vary from 30 to 0.3 μl. Test times vary from 5 seconds to 2 minutes (modern meters typically require less than 15 seconds). A blood glucose meter is an electronic device for measuring the blood glucose level. A relatively small drop of blood is placed on a disposable test strip which interfaces with a digital meter.

The urine test strip test for blood is based on hemoglobin's pseudo peroxidase activity in catalysing a reaction between hydrogen peroxide and the chromogen tetramethylbenzidine in order to produce a dark blue oxidation product. [6] [13] the resultant colour can vary between green and dark blue depending on the amount of hemoglobin. [13]

Fresh bacterial preparations should be used. After colonies have grown on the medium, 2-3 drops of the reagent DMPD are added to the surface of each organism to be tested. A positive test (OX+) will result in a color change violet to purple, within 10–30 seconds. A negative test (OX-) will result in a light-pink or absence of coloration.
