Diagnostic - CombiScreen Test Strips - 5 types

Excellent ascorbic acid protection for glucose and blood Ascorbic acid (vitamin C) is ingested through foods, dietary supplements and as a preservative. Excess ascorbic acid is excreted in the urine and observed in a high proportion of the population. However, ascorbic acid inhibits the blood and glucose test pad reaction, which may cause false-negative results in the presence of hematuria or glucosuria and in consequence delay of necessary diagnostic or therapeutic measures. Therefore, the CombiScreen® PLUS urine test strips are equipped with an active protection of the glucose and blood test pad, which largely eliminates the interference with ascorbic acid. The classic CombiScreen® urine test strips do not include an ascorbic acid protection. However, a test pad indicates the level of ascorbic acid in the urine to provide a hint of possible interferences.
