Introduction

A high red blood cell count in routine urinalysis may be caused by conditions such as cystitis, urethritis, or glomerulonephritis, and treatment should be targeted according to the underlying cause. Besides these, it could also be due to pyelonephritis; patients should seek timely medical care. Additionally, maintaining local skin cleanliness and hygiene, along with frequent changing and washing of clothes, can help reduce bacterial growth and promote recovery from the illness.

Elevated red blood cells in a routine urine test may be caused by conditions such as cystitis, urethritis, or glomerulonephritis. Treatment should be targeted according to the underlying cause, as detailed below:

1. Cystitis

Cystitis can lead to damage of the bladder mucosa, manifesting as itching, pain, and difficulty urinating. In severe cases, it may cause hematuria (blood in urine). During examination, an abnormally high number of red blood cells in the urine may be observed. Under a doctor's guidance, medications such as amoxicillin capsules, cefixime capsules, or azithromycin dispersible tablets can be used for treatment.

2. Urethritis

If a patient already has urethritis, inflammation in the urinary system may occur, damaging local tissues and leading to hematuria, swelling, and pain. Test results may show elevated red blood cells in the urine. It is important to follow medical advice and take medications such as levofloxacin hydrochloride tablets, ciprofloxacin hydrochloride capsules, or moxifloxacin hydrochloride tablets for treatment.

3. Glomerulonephritis

Glomerulonephritis can impair kidney function, causing red blood cells to accumulate in the body. Examination results will reveal an increased number of red blood cells. Treatment should follow medical recommendations and may include medications such as cyclophosphamide tablets, penicillin V potassium tablets, or cefuroxime axetil tablets.

In addition to the above causes, elevated red blood cells in urine may also result from pyelonephritis. Patients should seek timely medical treatment. Additionally, maintaining cleanliness and hygiene of the local skin, along with frequent changing and washing of clothes, can help reduce bacterial growth and support recovery from the illness.

What diseases can be detected through a routine urinalysis?

Under normal circumstances, a routine urinalysis may detect diseases such as urethritis, cystitis, pyelonephritis, glomerulonephritis, diabetes, and hyperuricemia. Urinalysis is a simple diagnostic tool, but it only serves as a clue for disease diagnosis. If the results of a routine urinalysis are abnormal, further diagnosis usually requires correlation with the patient's symptoms.

Under normal circumstances, urine culture is a commonly used medical test method. By culturing urine samples for various pathogens, it helps to identify the causative agents of urinary tract infections. Urine culture can detect diseases such as urethritis, cystitis, ureteritis, prostatitis, and vaginitis. Before undergoing a urine culture, it is important to maintain personal hygiene and keep the perineal area clean.

Can compound diazepam tablets be detected in a urine test after consumption?

Diazepam compound tablets belong to the benzodiazepine class of drugs. The main active ingredient, diazepam, can be metabolized and excreted from the body through urine. If a specific drug screening is conducted, such as testing for benzodiazepine concentrations, the urine test may yield a positive result. However, routine urinalysis primarily focuses on indicators such as white blood cells, red blood cells, and protein levels, which are used to assess the health status of the urinary system.

Does prolonged menstrual bleeding affect urine test results?

In general, having an ongoing menstrual period can affect urine test results, potentially causing abnormalities that interfere with the doctor's assessment. Routine urinalysis is therefore not recommended during this time. However, if a urine test is necessary due to special circumstances, clean the external genitalia with warm water beforehand to prevent menstrual blood from contaminating the sample. Collect a midstream urine specimen for testing to minimize contamination as much as possible.

What tests should be done for a woman with right lower abdominal pain?

Women with right lower abdominal pain generally need to undergo abdominal ultrasound, complete blood count (CBC), urinalysis, gynecological ultrasound, and abdominal CT scan. Abdominal ultrasound can clearly visualize the morphology and structure of abdominal organs such as the appendix, gallbladder, and intestines, helping to identify conditions such as appendicitis, gallstones, or intestinal obstruction. This non-invasive examination provides rapid initial diagnostic information.

I have a history of masturbation and recently often experience soreness in my lower back. Could this be kidney deficiency?

In general, whether frequent lower back pain and a history of masturbation indicate kidney deficiency should be determined based on specific symptoms, overall physical condition, and medical examination results. In any case, it is recommended to first visit a hospital for tests such as urinalysis, kidney function assessment, and lumbar spine imaging to rule out organic conditions such as kidney stones, nephritis, or herniated discs; also, avoid prolonged sitting in daily life.

What does drinking water before a physical examination affect?

Drinking water before a medical examination may generally affect blood tests, abdominal ultrasound, urinalysis, gastrointestinal examinations, and blood glucose measurements. Consuming large amounts of water can dilute the blood, potentially leading to lower levels of hemoglobin and hematocrit, which may interfere with the assessment of conditions such as anemia. It may also slightly reduce the measured values of blood lipids and glucose.
