Introduction

A single plus sign for occult blood in urine may be caused by intense exercise, menstruation, urethritis, glomerulonephritis, kidney stones, etc., and management should be based on the specific cause. High-intensity exercise may lead to temporary presence of red blood cells in urine. If urinalysis results are abnormal, it is recommended to seek medical attention promptly, complete further examinations, and follow medical advice for appropriate management.

One plus sign for occult blood in urine may be caused by intense exercise, menstruation, urethritis, glomerulonephritis, kidney stones, etc., and appropriate measures can be taken according to the specific situation. Detailed analysis is as follows:

1. Intense exercise: High-intensity physical activity may lead to temporary red blood cells appearing in the urine. Usually no special treatment is required, and it resolves spontaneously after rest.

2. Menstruation: During their menstrual period, women may show a false-positive result for occult blood in urine tests. This is generally normal. It is recommended to avoid urine testing during menstruation to obtain accurate results.

3. Urethritis: Bacterial invasion of the urethra causes inflammation, possibly damaging the urethral wall and allowing red blood cells to enter the urine. It is recommended to follow medical advice and take medications such as azithromycin granules, cefixime granules, or roxithromycin tablets to reduce inflammation.

4. Glomerulonephritis: Glomerulonephritis is a kidney disease that may damage the glomerular filtration membrane, allowing red blood cells to leak into the urine. Patients may use furosemide injection, roxithromycin tablets, methylprednisolone tablets, or other medications under a doctor's guidance to relieve symptoms.

5. Kidney stones: As kidney stones move, they may scratch the urinary tract mucosa, causing red blood cells to appear in the urine. It is recommended to follow medical advice and use potassium sodium citrate granules, Pishi Granules, or Shenshitong Granules to help improve the condition.

If routine urinalysis shows abnormal results, it is advisable to seek timely medical attention, complete further examinations, and follow medical instructions for proper management.
