Heller S Test

The Heller S Test is a method of analyzing urine that allows you to determine the presence of protein (albumin) in it. This test is one of the most common methods for diagnosing various kidney and urinary tract diseases.

The principle of the test is that the same amount of pure nitric acid is carefully added to a certain amount of urine in a separate test tube. If albumin is present in the urine, a white ring forms at the junction of these fluids. Thus, the appearance of a ring indicates the presence of protein in the urine.

However, it should be borne in mind that a similar result can be obtained if some drugs are present in the urine or if it is very concentrated. The appearance of a dark brown ring indicates the presence of an abnormally high content of potassium indoxyl sulfate (indicanurium) in the urine.

Although the Heller test is a simple and quick diagnostic method, its results are not always accurate. For a more accurate assessment of protein content in urine, it is recommended to conduct more complex and accurate research methods.

In general, the Heller test is one of the important methods for diagnosing kidney and urinary tract diseases, but its results must be interpreted with caution and always confirmed by more accurate research methods.



The Heller test is one of the methods for determining the presence of protein in the urine, which is used to diagnose various diseases of the kidneys and urinary tract. This test was developed in 1931 by American physician Henry Geller.

To perform the Heller test, you take a small amount of urine and add an equal amount of nitric acid, which is a strong acid. When these two fluids interact, a white ring forms on the surface of the urine. If there is protein in the urine, this ring will be visible. However, this test can also be false positive if there are certain medications in the urine or if it is very concentrated.

If a white ring is found in the urine, this means that it contains protein. This may indicate various kidney diseases, such as glomerulonephritis, pyelonephritis, nephrotic syndrome, etc. This test can also be used to diagnose urinary tract diseases such as cystitis, urethritis, etc.

However, the Heller test is not the only method for determining the presence of protein in the urine. There are many other methods that can more accurately determine the presence of protein in the urine and diagnose various diseases of the kidneys and urinary tract.



The Heller test, or Heller S test, is a method of determining the presence of protein (albumin) in urine by adding nitric acid to a specified amount of urine. If albumin is present in the urine, a white ring forms on the surface of the liquid. If a ring does not form, this may indicate the presence of certain medications or very concentrated urine.

However, the appearance of a dark brown ring may also indicate the presence of abnormal amounts of potassium indoxyl sulfate in the urine (see indicanuria). Indicanuria is a sign of kidney or liver disease and requires additional examination.

The Heller test is a simple and quick method to determine the presence of albumin in urine, which can be useful in diagnosing various diseases related to the kidneys or liver. However, please note that this test is not 100% accurate and may give false results in some cases, so it should only be used as a complementary diagnostic method.
