For rapid detection of multiple analytes in human urine. For professional in vitro diagnostic use only.
The Reactif 5B urinalysis strips are solid plastic strips on which multiple, separated reagent fields are applied. The test is for the qualitative and semi-quantitative detection of the following analytes in urine: glucose, ketone (acetoacetic acid), blood, pH and protein. The Reactif urinalysis strips are intended for single use at sites close to the patient (point of care) and central laboratories.
The cardboard label lists the respective analytes - compare the corresponding analyte with the fields on the colour scale. The Reactif urinalysis strips can be read optically as well as evaluated with the help of the urinalysis device and are intended for professional use only.
In the course of an illness or when the body is malfunctioning, urine undergoes many changes before the blood composition changes to a clearly recognisable extent. Urinalysis is a useful procedure as an indicator of health or disease, and as such is used in routine health screening. The Reactif urinalysis strip can be used in determining general health and helps in the diagnosis and monitoring of metabolic diseases or systemic diseases affecting kidney function, endocrine disorders and urinary tract diseases or disorders.
Blood is often found in the urine of women during menstruation. The significance of detected traces may vary depending on the patient and clinical assessment is required for these samples.
Glucose should not be detectable in normal urine. Small amounts of glucose may be excreted by the kidney. Glucose concentrations that continuously exceed 100 mg/dL are considered abnormal.
Ketones are not normally present in urine. Detectable ketone concentrations may occur in the urine due to physiological stress conditions such as dieting, pregnancy and exercise. During starvation or other abnormal carbohydrate metabolism, extremely high urinary ketone concentrations may occur before serum ketones are elevated.
The expected range in normal neonatal urine samples is pH 5-7. In other normal urine samples, the expected range is pH 4.5-8, with pH 6 as the average result.
The colours range from yellow to yellow-green for negative results and from green to green-blue for positive results. A normal kidney can excrete 1-14 mg/dL of protein. Significant proteinuria is indicated when a colour is assigned to any colour field indicating more than trace. Clinical judgement is required to assign significance to detected traces.
