one-third of those affected, IgA nephropathy is characterised by episodes of visible haematuria coinciding with intercurrent Exposure of unpreserved urine to room temperature for a period of time can change pH and increase micro-organisms. If it cannot be tested immediately, the sample needs to be stored in line with the reagent strip manufacturer’s instructions or at 2-4°C and then brought to room temperature (15-20°C) before testing; The detection of glucose by test strips is based on the enzymatic reaction of glucose oxidase. This enzyme catalyses the oxidation of glucose by atmospheric oxygen to form gluconic acid and hydrogen peroxide. A second linked reaction, mediated by a peroxidase, catalyses the reaction between the peroxide and a chromogen (a substance that acquires colour after a chemical reaction) to form a coloured compound that indicates the glucose concentration.

A number of substances interfere with the Ehrlich reaction on the Multistix strip: porphobilinogen, indican, p-amino salicylic acid, sulphonamide, methyldopa, procaine and chlorpromazine. The test should be carried out at room temperature as the reaction's sensitivity increases with temperature. Poorly stored samples can yield false negative results as the urobilinogen suffers photo oxidation to urobilin that does not react. The formaldehyde used as a preservative produces false negatives in both reactions.
