Roche - Combur 9 Test Strips (x100)

Product Information

Please note, Combur 7 strips can no longer be used with the Urysis 1100, you will need to use the Combur 10 Test UX Strips with this machine. albumin quantification by ACR provides increased sensitivity and precision for detection of lower, but clinically significant

Rodgers M, Nixon J, Hempel S, et al. Diagnostic tests and algorithms used in the investigation of haematuria: systematic Intestinal bacteria convert the conjugated bilirubin that is excreted by the bile duct into the intestine into urobilinogen and stercobilinogen. Part of the urobilinogen is reabsorbed in the intestine then circulated in the blood to the liver where it is excreted. A small part of this recirculated urobilinogen is filtered out by the kidneys and appears in urine (less than 1mg/dL urine). The stercobilinogen can not be reabsorbed and remains in the intestine. [15] [16]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. [16] Urinary infections [ edit ]

Patients with IgA nephropathy who only have non-visible haematuria and no, or minimal, proteinuria, normal blood pressureThe test does not measure beta-hydroxybutyric acid and it is only weakly sensitive to acetone when glycine is added to the reaction. However, as these compounds are derived from the acetoacetic acid their existence can be assumed and a separate test is not therefore necessary. Those medicines that contain sulfhydryl groups, such as mercaptoethane sulphonate Na ( Mesna) and captopril and L-DOPA can give atypical colouring. A false negative can occur in samples that have not been adequately stored due to volatilization and bacterial degradation. Non-visible haematuria is regarded as significant once transient causes, e.g. urinary tract infection (UTI) or exercise, of the external genitalia reduces contamination. 3 If it is necessary to collect urine from patients with

Women who are pregnant, or people who have a suspected allergy to the contrast media, may not be suitable for CTU imaging.The test method consists of immersing the test strip completely in a well mixed sample of urine for a short period of time, then extracting it from the container and supporting the edge of the strip over the mouth of the container to remove excess urine. The strip is then left to stand for the time necessary for the reactions to occur (usually 1 to 2 minutes), and finally the colours that appear are compared against the chromatic scale provided by the manufacturer.

J Am Board Fam Med. 2008;2 A portfolio of semi-automated systems for Point of Care and mid volume laboratory testing needs: Urisys 1100 ® and cobas u 411 urine analyzer Reliable diagnosis - Even minute pathological changes in the urine cause distinct color changes in the test fields. This makes urine testing with Combur-Test ® strips the first step on the way to a reliable diagnosis in both clinics and practices.
