Microalbumin

Urine is collected for the day. The first morning portion in the toilet, all subsequent ones during the day, at night, and the morning portion the next day (for example, from 6:00 a.m. to 6:00 a.m. the next day) are collected in one container, which is stored in a cool place protected from sunlight (at a temperature of 4-8 C).
– it is imperative to indicate the daily volume of urine collected and the volume of fluid consumed per day;
– all collected daily urine is mixed, and 40-50 ml is poured into a separate container and delivered to the laboratory within 2 hours;
– Urine without added preservatives is delivered to the MediLab+ laboratory.

Microalbumin is a small protein that is not normally found in urine or is found in very low concentrations. However, its detection in urine can be an important indicator of urinary tract health and kidney function. Urine biochemistry, including determination of microalbumin levels, helps to detect a variety of disorders and diseases related to the kidneys and urinary tract.

The main functions of the kidneys include removing waste products and toxins from the body, regulating fluid and electrolyte balance, and maintaining normal blood pressure. The kidneys filter the blood and remove harmful substances through the urinary tract. If the kidneys are not working properly, this can lead to increased protein excretion through the urinary tract, including microalbumin.

Microalbumin levels in the urine are measured using special tests, such as the microalbuminuria test. This test can detect even small amounts of microalbumin in the urine that cannot be detected using standard methods.

The main causes of increased levels of microalbumin in the urine include:

1. Diabetic nephropathy: This is a complication of diabetes that can lead to kidney damage and the leakage of microalbumin into the urine.
2. Hypertension: High blood pressure can damage the kidneys and affect microalbumin excretion.
3. Nephritis: Kidney diseases, such as glomerulonephritis, can lead to increased levels of microalbumin in the urine.
4. Other kidney diseases: Various other kidney diseases, including cystic changes and other abnormalities, can also affect microalbumin levels.
5. Toxic effects: Taking certain medications or coming into contact with toxic substances can cause increased levels of microalbumin in the urine.

It is important to note that elevated levels of microalbumin in the urine may be an early sign of kidney problems that can be more easily detected and treated in the early stages. Therefore, regular urine chemistry tests, including microalbumin testing, are recommended for individuals at risk of developing kidney disease, such as diabetics and those with hypertension.

Doctors can use information about microalbumin levels to diagnose and monitor kidney and urinary tract diseases, and prescribe treatments to maintain kidney function and prevent disease progression.

In summary, microalbumin and urine chemistry tests are important tools for assessing the health of the kidneys and urinary tract. They allow for early detection of potential problems and initiation of treatment to preserve kidney function and maintain overall health. Regular medical check-ups and consultation with a doctor are key steps in maintaining kidney health.
