Can I take a urine test during my period?

Menstruation is a special period. During menstruation, the endocrine function of women's bodies is not very perfect, which may lead to misdiagnosis during the examination. Therefore, you must be careful during menstruation and try not to do urine tests. Urine may carry a small amount of red blood cells, which will lead to an increase in red blood cells in urine, different test results, and even misdiagnosis. You must wait until the end of menstruation to have a check-up.

Urine testing during menstruation may cause a small amount of red blood cells to be present in the urine, leading to an increase in red blood cells in the urine.

Suggestions: It is best to stagger the menstrual period to do urine test.

1. The kidneys are responsible for the formation of urine. Blood passes through the glomerulus, and all liquid filtered out except blood cells and protein is selectively reabsorbed by the renal tubules to form urine. It is then stored in the bladder through the ureters and excreted from the body through the urethra after a certain period of time.

2. Summary of normal values ​​for general urine examination

Normal value of test items

Color: clear or light yellow, transparent

Sugar qualitative 2～3mg100ml (negative)

Protein qualitative negative

Specific gravity 1.010~1.030 (specific gravity of the first urine in the morning is greater than 1.018)

Acidity (PH): Weakly acidic

Microscopic examination

Red blood cells less than 3/high power field

Less than 5 white blood cells/high power field

No or occasional hyaline casts

Urobilinogen is negative or weakly positive (negative after 20-fold dilution)

Urine bilirubin qualitative test negative

Urine bilirubin negative

Acetone negative

3. Numbers represent meaning

Urine color

Turbid urine or color changes such as hematuria, soy sauce color, or significantly darker urine color all indicate pathological significance.

Urine sugar

Positive urine sugar can be seen in diabetes, hyperthyroidism, pancreatitis, pancreatic cancer, and after long-term glucocorticoid treatment.

Urine protein

Positive urine protein can be divided into physiological and pathological. The former can be seen after strenuous activity, high fever or intake of large amounts of protein, which are transient and temporary urine protein. Pathological proteinuria can be seen in various kidney diseases such as nephritis, nephrotic syndrome, renal artery sclerosis and systemic diseases such as heart failure, systemic lupus erythematosus, and multiple myeloma.

Urine specific gravity

Urine specific gravity fixed at 1.010±0.003 is called "diabetic urine", which is seen in the late stage of chronic nephritis. Urine specific gravity less than 1.018 throughout the day indicates renal concentrating insufficiency and diabetes insipidus. Increased urine specific gravity occurs after dehydration and hypovolemia.
