Urinalysis: color and transparency

In the blanks on a urine test there is always a line color "transparency". Modern laboratory equipment can give detailed descriptions of your urine, but it is but by the color of urine can say a lot about the health of the patient. In the normal urine of a healthy person, usually transparent, straw-yellow.

Color

Color of urine in norm due to the presence of pigments: urobilin, urochrome, uroerythrin, hematoporphyrin. When the higher specific gravity of the urine becomes more saturated color, while low values of relative density, it becomes almost colorless. The polyuria caused by increased drinking regime or diuretics or food color is weakly saturated. The pale color of urine is typical for patients with diabetes, chronic glomerulonephritis, chronic renal failure. The color is also influenced by medications, vitamins (urine may become bright yellow), food (after eating beets, urine often becomes pink).

Newborns colorless urine becomes amber-brown with physiological jaundice. Infants pee often lighter in color than adults.

A rich, dark color can be while limiting drinking, emergency Department sweat. This is not a pathology called physiological hyperchromia. In pathological cases, the urine becomes too saturated color if oliguria due to the formation of edema in the tissues, dyspepsia, fever. With increased destruction of red blood cells (hemolytic anemia, poor blood transfusion) urine becomes sharply hyperchromic brown or red-brown color. In acute glomerulonephritis or poisoning acetic acid (in this case, is enhanced destruction of red blood cells), urine has a so-called "color of meat slops".

The color of fresh blood due to the presence of a large number of red blood cells in the urine (bleeding tumors of the bladder).

Green urine becomes when jaundice caused by obstruction of the biliary tract (stones, Giardia, tumors). In this case, bilirubin, turns into a green color, which gives the characteristic color of the urine.

The so-called urine color "beer" is a characteristic sign of acute hepatitis. A milky-white color gives grounds to suspect fatty degeneration of the kidneys, lymph, pus in the urine, or the excess of salts of phosphates.

Normal urine should be clear. When standing may show a slight haze that is not a sign of pathology. Cloudy urine due to loss of salts (urates, amorphous phosphates, oxalates), presence of mucus, a large number of cellular elements (leukocytes, erythrocytes, epithelial cells), bacteria, and drops of fat. The cause of turbidity will become clear upon examination of urine sediment under the microscope. In this case, the technician will indicate which items and in what approximate quantities have been found. So, if the urine had a white haze, the results on the form can be indicated by the presence of phosphates, or in front of the column "leukocytes" will be written, for example, "entirely in the p/SP (field of view).
