Sulkovich's trial. Indication, technique

Laboratory methods of research in medicineallow to see the presence of inflammatory processes in the body or to point out specific diseases (for example, pathologies of the blood system, the presence of kidney failure, lack of digestive enzymes, diabetes mellitus). Sometimes due to the analysis it is possible to understand the cause of the disorder (viral or microbial agent).

There are many methods for assessing the qualityand the quantitative composition of urine. These include the following: general analysis, Sulkovich's test, Nechiporenko, Zimnitsky, Addis-Kakovski, Amburge, etc. Each of these methods helps to suspect a certain pathology of the urogenital system, as well as the presence of other diseases.

Sulkovich's test - for what is used?

Sulkovich test

Evaluation of urine by Sulkovich is designed to,to determine the content of calcium in it. This method is used for suspected rickets. The disease is associated with the incorrect formation of bones due to a lack of calcium in the body. This pathology is widespread among infants who do not receive a prophylactic dose of vitamin D or lacks sunlight. Sulkovich's test in this case is relative, and not absolute, so the diagnosis of rickets only with its help is not correct. More often this analysis is used to control the dose of vitamin D and avoid its overdose, which is manifested by hypercalcemia.

What is dangerous hypercalcemia?

Sulkovichi trial

The state in which the body is located whenexcess calcium content is very dangerous. They are accompanied by many diseases, for example, hypervitaminosis, hormonal disorders, sarcoidosis, tumors, etc. Excess of calcium leads to the defeat of all organs and systems, but most affected by bone, central nervous system, intestines and blood vessels. The pathological condition is expressed by a violation of consciousness (up to coma), muscle weakness or tension, arterial hypertension, a decrease in the heart rate, the appearance of kidney stones, and impaired glomerular filtration. Since calcium is absorbed in the gastrointestinal tract, an increase in its level leads to digestive disorders, including nausea, vomiting, constipation. In the bone system, the tissues become denser, which is accompanied by impaired movement and soreness.

Sulkovich's trial. Explanation of results

Sulkovicha negative test

In order to avoid such dangerous conditions,as hyper- and hypocalcemia, conduct a Sulkovich trial. The mechanism of the procedure is to introduce into the urine of the patient a special substance that contains oxalic acid. In the presence of calcium in the analysis, the Sulkovich reagent interacts with it, which is determined by the precipitation of a turbid precipitate. The sample is evaluated on a five-point system (from 0 to 4). In this case, the mean values ​​are considered normal. As with increased, and with a lower content of calcium in the body, the result will show Sulkovich's trial. Explanation:

1. Complete lack of reaction (transparency of urine) allows you to put 0 points. This result indicates a hypocalcemia, in this case the Sulkovich trial is negative.

2. An insignificant degree of turbidity indicates 1-2 points. This is a normal result, that is, the amount of calcium in the body is sufficient.

3. With a strongly turbid urine is exposed 3 and 4 degree. This suggests hypercalcemia.

Indication for the sample

Sulkovich test

The Sulkovich test is a common methodDiagnosis, which is used to identify a variety of pathologies. Assign this analysis to many specialists, most often nephrologists, endocrinologists, oncologists, gastroenterologists, neuropathologists. Such a number of specialists is connected with the fact that the symptoms of excess or lack of calcium are expressed in the defeat of all systems, therefore it is necessary to conduct a qualitative differential diagnosis. The indications are the following: suspicion of hyper- or hypothyroidism, sarcoidosis, increased intake of vitamins D and A. In oncology, this test is used to detect calcium-producing tumors that can be located in any organ, most often in the thyroid gland. Sulkovich's test in children is necessary to control the use of vitamin D, which is widely used in pediatric practice for the prevention of rickets.

Technique for collecting analysis

Sulkovich test in children

When this laboratoryresearch, parents have questions about what is the Sulkovich test, how to take the analysis, why it is needed, etc. Dishes for urine should be dry and clean, as this factor can affect the wrong result. Before collecting the analysis, you should carefully wash your genitals with soap. Then release a small jet of morning urine into the toilet bowl, the rest - in the dishes. Before taking the test, you need to limit yourself to drinking mineral water, dairy products, greens, alcoholic beverages and coffee. Violation of this rule leads to a false positive Sulkovich's trial. Limitation of foods containing large amounts of calcium is recommended within 3 days before the test.

Principles of treatment of hyper- and hypocalcemia

With a sharply positive or negative sampleSulkovich needs proper medication. When hypercalcemia is important, first find out the cause of the disease. If the fault is the use of vitamin D, then it should be canceled. With a negative sample shows sour-milk products, protein food, ground eggshell. Calcium preparations should be administered under strict control so that the opposite symptoms do not develop.
