Tubular Test

A canalicular (nasal) test is a special test for diagnosing certain diseases of the upper respiratory tract. It allows you to determine the presence of infection or inflammation in the sinuses. This test is also known as a tear test because it involves taking a sample of fluid from the tear gland.

The tubular test is an important test for identifying sinusitis diseases. Sinusitis is an inflammation of the upper respiratory tract that can be caused by various infections, allergies, or problems with the immune system. Its symptoms include nasal congestion, headache, fever and runny nose.

To perform a tubular test, the doctor uses special equipment: a tubule. These are small tubes that are inserted into the patient's nose and collect a sample of tears or mucus from the sinus cavity. Once a fluid sample is collected, it is sent to a laboratory for analysis.

Tubular test results can be very accurate and reliable. For example, if a patient has an elevated protein level in a plasma sample, this may indicate the presence of sinusitis and the need for further testing. In general, tubular sampling is a very accurate and informative test for diagnosing various diseases of the upper respiratory tract and resolving questions about treatment. It is important to consult a doctor before performing this test and follow his or her recommendations.

The canalicular test, or, as it is also called, the nasolacrimal test, is a method for diagnosing immunity to viral diseases, including COVID-19. The essence of this method is to analyze mucous discharge from the patient’s nose.

The mechanism of this method is based on the fact that when infected with viral diseases, the patient develops inflammatory processes, which are accompanied by the release of various biological fluids. It could be mucus or tears. It is these secretions that are examined using a tubular test.

A tubular test can be performed both during the acute period of the disease and after recovery. If the test result is positive, conclusions can be drawn about the patient’s immunity, which protected him from infection. However, in order to obtain a reliable result, it is necessary to adhere to certain rules for collecting biomaterial. First of all, proper preparation for tubular plug diagnostics and analysis for coronavirus is important.

In addition, there are certain restrictions and recommendations for those who undergo such diagnostics. For example, before conducting a tubular test to determine whether a person has immunoglobulins, it is recommended to avoid the use of chemicals to clean the nose and monitor oral hygiene as much as possible. It is also advisable to refrain from taking antibiotics and alcohol. The reliability of the result will depend on the competent conduct of the test and on the discipline of the researcher conducting it. Any slight deviation from the usual pattern can negatively affect the diagnostic result.
