The interpretation of the test results
Test result judge:
Sign specified time according to the bottle, with reference to the standard color code judgment test results and records. Suspicious, repeatable test, when positive urine specimen, need further examination

Glucose: The experimental area of glucose detection specificity, in addition to sugar, other substances in urine can not be any one of a positive detection result. Paper and can make positive color change reaction in the urine, if the ascorbic acid contained less than 0.28mmol / L, at least to the content of glucose 2.2mmol / L. If the urine can ascorbic acid concentrations greater than 2.84mmol / L, or ketone body concentrations higher than 4mmol / L glucose content in the sample 4-7mmol / L showed a false negative reactions. When the specific gravity of the urine increased, decreased glucose test reaction. Reactivity also due to temperature change. Under normal circumstances, there may be a small amount of glucose excreted via the kidneys, but this small amount is less than the detection sensitivity of the test strip.

Bilirubin: Under normal circumstances, can not be detected in the urine of bilirubin. If the presence of trace amounts of bilirubin in urine, abnormal enough to prompt the need for further examination. When some of the metabolites of drugs, such as pyridine metabolites and s- oxindole aldehyde acid can cause false positive results in urine ascorbic acid concentrations greater than 1.42mmol / L, can cause false negative results. When the results were negative hemolytic jaundice.

Ketone : This study flora acetoacetate in urine, but does not react with urine acetone and β- hydroxybutyrate. Normal urine sample is usually negative, some high gravity / low PH of the urine will increase its reactivity and trace ketones coloration. False positive or abnormal coloration seen in large volume of acetone gum benzene, acetone, plastic, α- keto acid into the sample levodopa metabolite contained in the sample or a dye.

Specific Gravity: The urine dipstick can determine the ratio of between 1.005 and 1.030, this method a good correlation with refraction coefficient method and its error is within 0.005. In order to increase the accuracy, when urine PH 6.5 or higher, plus 0.005 in their reading, and can automatically adjust the urine analyzer. In the urine test results from some nonionic ingredients, such as glucose, are not affected by opaque color dye. Highly buffer alkaline urine will be lower compared with other methods of numerical; When the protein in the urine (1-7.5 g/L), also can make rising proportion of the value.

Blood: This experiment of hemoglobin is very sensitive and can be used as a supplement to the microscopic examination. This paper is Vc interference formula, even if the content of ascorbic acid in the urine as high as 2.84 tendency for L, also won't appear false negative results. But for high density and high bad blood acid urine sample, reaction will have lower sensitivity. Occult blood should be distinguished from the menstrual period women's blood in the urine. Certain oxidizing pollutants, such as hypochlorite can lead to false positives, microbes associated with urinary tract infection in the peroxidase can also cause false positive results.

PH: PH test area usually within 1 unit test values. To the naked eye measurement range of 5.0-8.5, instrument measuring range is 5-9.

Protein: This test area than in albumin globulin, hemoglobin, this a zhou protein and glycoprotein is more sensitive, so the result of a "negative" cannot be ruled out this type of protein in the urine samples. Under normal circumstances, the kidney will drain a small amount of protein, but the conventional method can't check out, such as color than "trace" standard block deep means have proteinuria, need further examination. High alkaline urine buffer can lead to false positive results, if the urine samples by quaternary ammonium salt compounds or some cleaner, preservatives pollution can also cause false positive results

Urobilinogen:This test can detect in the urine concentration as low as 3 mu mol/L (approximately 0.2 Ehrlich) uric bravery of the original. In normal urine uric bravery original content is 3.2-16 mu mol/L. 32 mu mol/L could be the result of the from the normal to the abnormal changes of the critical value, need further examination. When the normal cannot be ruled out completely occlusive disorders of jaundice. In high concentration of urine aminobenzoic acid can cause atypical color reaction, urine exist formaldehyde can make for false negative results

Nitrite: This experimental area of nitrite is the specificity, don't react with normal urine excretion of other substances. The test is based on the premise that gram-negative bacteria effect and make the urine nitrate to nitrite. Any appear even pink should be judged positive results, shows a sample of more than 105 / mL number of gram-positive bacteria. However, the negative results cannot be said without the presence of bacteria in the urine, negative results seen in the transformation of nitrate bacteria, also may be due to urine is not enough time left in the bladder (4 hours) to complete the transformation of nitrate to nitrite. High proportion of urine can reduce the reactivity of this experiment, high bad blood acid (1.42 or higher tendency/L) can make urine nitrite a false negative result

Leukocyte: Urine samples of normal leukocytes were negative results. Positive results and appeared again and again, it is very important in clinic, the need for further examination. Due to pollution, vaginal discharge in women occasionally get a positive result in the urine sample. High glucose concentration (tendency for 160 / L) or high proportion of urine can reduce the result of the experiment, high concentrations of drugs (e.g., cephradine) can also cause false negative results.

Ascorbic acid: Ascorbic acid can be used to measure the content of 0, 50 mg/dL, through the test can know the level of ascorbic acid in the urine of glucose, bilirubin, occult blood, the influence degree of the determination of nitrite, etc. When urine sample contains antioxidants (such as potassium permanganate, sodium hypochlorite), will affect the sensitivity of this test

Creatinine: Under the condition of peroxides, creatinine and sulphate generate complex, catalytic hydroxyl peroxide isopropyl benzene and TMB, response range from orange to green, the color change of the final to blue, a color change is proportional to the content of creatinine

Calcium: Calcium ions in urine in alkaline conditions, combined with adjacent a phenolphthalein complexation ketone in the test paper, generating a complex of amaranth, adding suitable amount of the delta - hydroxyquinoline can eliminate interference magnesium ions


Micro albumin: Trace than globulin to albumin, hemoglobin, albumin project ~ Bence Jones's protein and mucin sensitive, so check out a "negative" result does not mean that do not have these proteins. This project can detect urinary albumin, sensitive to the sensitivity of other proteins than albumin low several times. For highly buffer, alkaline urine, are likely to get false positive results. If the urine is quaternary ammonium salt compounds and certain preservatives or detergent pollution can also cause false positives, visible to the naked eye hematuria may also affect protein test
The limitations of testing method

Urine analysis in the urine dipstick test method is limited to the various ingredients for qualitative and semi-quantitative measurement, so the products in clinical as auxiliary diagnosis methods, only not as on the basis of diagnosis and treatment of disease of disease of further confirmation should be combined with other testing means.

Attention
Test strip shall be stored in dry environment, should avoid direct sunlight, high temperature and humidity

Test paper in a desiccant inside the bottle, test paper should be timely after using out of the bottle

Please according to the time stated on the various projects to determine test results, in addition to white blood cells must be in 2 minutes and other projects are color within 1 minute. Color change after 2 minutes without clinical significance.

Such as paper not fully immersed in the urine, can cause color uneven, affect judgment
Paper from the urine, immediately slipped to excess urine, lest affect the results

In test sites have sexual material (acid, alkali, organic solvents, coal, etc.) or the use of oil, coal heating furnace, etc., will affect the correctness of the results.


Please in the bright place, such as fluorescent lamp) judgment result

By the time of glucose, occult blood (the) chlorate, bleaching powder, such as antioxidant effect, can be a false positive

When the urine sample is strongly basic, urine protein can be a false positive reactions, can be added to dilute acetic acid, make among them and after testing.

In the urine, such as a large number of ascorbic acid and nitrite, affects glucose, occult blood and bilirubin color reaction, but the product of Vc interference, the ascorbic acid concentration tendency for 2.84 / L, will not cause a false negatives of glucose, occult blood.
