![]() In general, collection time, transport, and storage conditions can be examined to determine the causes of error. For this reason, the College of American Pathologists (CAP) recommends that laboratories have a procedure for the correlation of microscopic and macroscopic results. This can be ruled out by doing a visual exam of the urine specimen prior to performing the dipstick. Abnormally coloured urine due to medications, food dyes, or vitamins can alter the colour change on dipstick test pads for tests other than colour. Another example is the effect of urine colour on urinalysis reagent test pads. This will confirm that the response for blood on the reagent strip is inaccurate. In this case, microscopic analysis will verify the presence of bacteria and possibly the lack of red blood cells. The microbial peroxidase activity can cause a false-positive reaction for blood. A false-positive result for blood can be obtained when a specimen contains infection-causing bacteria. When unexpected results are seen in urine measurements, they should be interpreted in the context of other analytes and clinical results that measure similar aspects of renal function.Īn example is blood and bacteria testing in routine urinalysis. There are many preanalytical variables that can introduce error into laboratory test results.
