Can I eat while doing urine test

Routine urine test is used to analyze whether a certain disease exists. Before doing the routine urine test, the doctor will give specific suggestions. The doctor will tell you whether you can eat or drink water for different types of tests. Usually you can drink water during a routine urine test. There are many contents in routine urine examination. During the examination, the patient's physical condition will be analyzed based on various values ​​such as urine color, transparency, acidity and alkalinity.

Can I eat while doing urine test?

Can you drink water during a routine urine test? Suggestions: Can you drink water during a routine urine test? The urine routine test depends on the specific requirements of the doctor who treats you. The urine routine test includes the morning urine test, which is the so-called test on an empty stomach without drinking water or eating. For example, a random urine test means that any urine you leave at the hospital can be tested. There is also a 24-hour routine urine test, but most people still have most random urine tests done in the hospital. If you want a special test, it depends on the doctor's instructions.

Urinalysis precautions

1. During the routine urine test, collect no less than 10 ml of urine. 2. Women are generally required to avoid collecting urine samples during their menstrual period to prevent vaginal secretions from mixing into the urine and affecting the test results. 3. It is best to collect midstream urine. 4. Urine should be collected in clean and dry containers, such as the disposable urine cup and urine test tube provided by the hospital. 5. The retained urine should be sent to the laboratory for examination as soon as possible, because if it is left for too long, problems such as glucose being decomposed by bacteria, tubular destruction, and cell lysis may occur, affecting the accuracy of the test results.

What does a routine urine test contain?

Urinalysis examination includes urine color, transparency, pH, red blood cells, white blood cells, epithelial cells, casts, protein, specific gravity and qualitative urine sugar.

(1) Urine color: The color of normal urine is mainly caused by urochrome, whose daily excretion is generally constant, so the depth of urine color changes with the amount of urine. Normal urine is straw yellow, while abnormal urine color may change due to factors such as food, medicine, pigments, and blood.

(2) Transparency: Normal fresh urine is mostly clear and transparent, except for women's urine which is slightly turbid. If left for too long, it will become slightly turbid. This is because the acidity and alkalinity of the urine change, and the mucus protein, nucleoprotein, etc. in the urine gradually precipitate.

(3) Acidity and alkalinity: Normal urine is slightly acidic, but can also be neutral or slightly alkaline. The acidity and alkalinity of urine depends largely on the type of diet, medications taken, and the type of disease.

(4) Cells: The cells that are clinically important in urine are red blood cells, white blood cells, and small round epithelial cells.

(5) Casts: Normal urine contains only a very small amount of albumin, no casts, or occasionally a few transparent casts. If one cast appears in the urine, it can reflect the condition of at least one renal unit, which is a sign of kidney disease and is of great significance for diagnosis.

(6) Protein: It is generally believed that the amount of protein excreted by a normal person per day is 40 to 80 mg, and at most 100 to 150 mg. Routine qualitative tests are negative. Pathological proteinuria is seen in glomerulonephritis, pyelonephritis, acute renal failure, hypertensive nephropathy, diabetic nephropathy, pregnancy poisoning, lupus nephritis, radiation nephritis and other inflammatory lesions in the kidney, poisoning, tumors, etc.

(7) Specific gravity: The specific gravity of urine is approximately between 1.015 and 1.025. The urine specific gravity of infants and young children is relatively low. The urine specific gravity is affected by age, water intake and sweating. The level of urine specific gravity mainly depends on the concentrating function of the kidneys, so measuring urine specific gravity can be used as one of the renal function tests.

(8) Qualitative analysis of urine sugar: Normal people may have trace amounts of glucose in their urine. The daily urine sugar content is 0.1 to 0.3 grams, and the maximum does not exceed 0.9 grams. The qualitative test is negative. Positive urine sugar is often seen in diseases such as renal glucosuria, diabetes and hyperthyroidism.
