Indigo Carmine Test

Indigo carmine test: an indicative method for studying kidney function

The indigo carmine test is an indicative method for a separate study of kidney function, which consists of observing through a cystoscope the discharge from the orifices of the ureters of urine stained with indigo carmine, previously injected intravenously or intramuscularly.

Indigo carmine is a dye that has the ability to be quickly excreted from the body through the kidneys. When indigo carmine is administered intravenously or intramuscularly, it is quickly distributed throughout the body and excreted through the kidneys into the urine.

Using the indigo carmine test, you can evaluate the function of each kidney separately. To do this, indigo carmine is first administered intravenously or intramuscularly, followed by observation of how dye-colored urine is released from individual ureters.

If both ureters are functioning normally, urine will be released from them at the same time and will have the same color. If one of the kidneys does not function properly, then urine will not be released from it or will have a different color.

The indigo carmine test allows you to quickly and accurately determine the presence of functional kidney disorders. It can be useful in diagnosing various kidney diseases such as stones, tumors, inflammation and others.

However, it should be noted that the indigo carmine test may not be safe for patients with certain kidney diseases. Therefore, the use of this method should only be carried out under the supervision of qualified medical personnel.

Indigo carmine test or Loaser test is a method of indicative study of the functions of the urinary tract. This is a simple way to determine the excretory capacity of the kidneys, so it is available to a wide range of patients. The method was discovered by the French physician Bernard Loazer. Due to its accessibility, simplicity and speed, this study

Indigo caramic test

Preyen (Preyen's test) is a method for detecting stones in urolithiasis by the presence of indigo carmine excreted in the urine after intravenous administration of indigo carmine or its methoxins dissolved in glucose. Urine is tested cystoscopically for the presence of melanozoonic stripes, signals that stones are passing from the urinary tract. All stones larger than 5 mm in diameter do not produce stripes or produce very faint stripes. Melanozone (semi-digested indigo carmine) is a reagent for coloring melanin - the coloring substance of skin, hair and pigment films. When melanosis accumulates in the urinary system, pigmentation reaches a maximum concentration, detected by the appearance of chocolate staining on the patient’s epidermis. In addition to specificity, the Preyen method is easy to perform and less traumatic

The indigo-caramal test (Preyen-Rothermus test) is used in the selection of patients for crushing, repositioning or removal of coral stone. Before the study
