Urine test strips 10 parameters

A one step urine test strip or dipstick test is a basic diagnostic tool used to determine pathological changes in a patient’s urine in standard urinalysis.

A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample. The test can often be read in as little as 60 to 120 seconds after dipping, although certain tests require longer. Routine testing of the urine with multiparameter strips is the first step in the diagnosis of a wide range of diseases. The analysis includes testing for the presence of proteins, glucose, ketones, hemoglobin, bilirubin, urobilinogen, acetone, nitrite and leucocytes as well as testing of pH and specific gravity or to test for infection by different pathogens.

The test strips consist of a ribbon made of plastic or paper of about 5 millimeter wide, plastic strips have pads impregnated with chemicals that react with the compounds present in urine producing a characteristic color. For the paper strips the reactants are absorbed directly onto the paper. Paper strips are often specific to a single reaction (e.g. pH measurement), while the strips with pads allow several determinations simultaneously.

There are strips which serve different purposes, such as qualitative strips that only determine if the sample is positive or negative, or there are semi-quantitative ones that in addition to providing a positive or negative reaction also provide an estimation of a quantitative result, in the latter the color reactions are approximately proportional to the concentration of the substance being tested for in the sample.The reading of the results is carried out by comparing the pad colors with a color scale provided by the manufacturer, no additional equipment is needed.

This type of analysis is very common in the control and monitoring of diabetic patients. The time taken for the appearance of the test results on the strip can vary from a few minutes after the test to 30 minutes after immersion of the strip in the urine (depending on the brand of product being used).

Semi-quantitative values are usually reported as: trace, 1+, 2+, 3+ and 4+; although tests can also be estimated as milligrams per decilitre. Automated readers of test strips also provide results using units from the International System of Units.

The test method consists of immersing the urine 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 colors that appear are compared against the chromatic scale provided by the manufacturer.

An improper technique can produce false results, for example, leukocytes and erythrocytes precipitate at the bottom of the container and may not be detected if the sample is not properly mixed, and in the same way, if an excess of urine remains on the strip after it has been removed from the test sample, may cause the reagents to leak from the pads onto adjacent pads resulting in mixing and distortion of the colors. To ensure that this does not occur it is recommended the edges of the strip are dried on absorbent paper.

Diseases Identified with a one step urine test strip

With the aid of routine examinations early symptoms of the following four groups can be identified:

    Diseases of the kidneys and the urinary tract

    Carbohydrate metabolism disorders (diabetes mellitus)

    Liver diseases and hemolytic disorders

   Urinary infections

Uses for one step urine test strip

Urine test strips can be used in many areas of the healthcare chain including screening for routine examinations, treatment monitoring, self-monitoring by patients and/or general preventive medicine.

Screening

Urine test strips are used for screening both in hospitals and in general practice. The aim of screening is early identification of likely patients by examination of large groups of the population. The importance of screening for diabetes and kidney disease amongst high-risk populations is becoming very high.

Treatment Monitoring

Treatment monitoring with the aid of urine test strips allows a health professional to check on the results of the prescribed therapy, and if necessary to introduce any changes into the course of therapy.

Self-monitoring by Patients

Self-monitoring with urine test strips under the guidance of a health professional is an effective method for monitoring the disease state. This applies particularly to diabetics, where the idea of self-monitoring of the metabolic status (determinations of glucose and ketenes) is self-evident.

General Preventive Medicine

Unsolicited self-testing has become a popular measure in recent years as various urine test strips become available via pharmacy and online stores. Self-monitoring for frequent urinary tract infections is a popular example as sufferers monitor their own urine on a daily basis and discuss the results with their health professional.

Veterinary

In veterinary medicine, especially in cats and dogs, the test strip can be used for urinalysis.
