What does it mean when a routine urine test shows occult blood +1?

Generally, occult blood +1 refers to 1+ occult blood in a routine urine test, meaning there is a small amount of hemoglobin in the urine. A finding of 1+ occult blood in a routine urinalysis may be caused by physiological factors such as strenuous exercise or excessive fatigue, or it could result from pathological conditions such as pyelonephritis or renal cysts. Depending on the underlying cause, patients can relieve discomfort through daily care, medication, or surgical treatment. Specific analyses are as follows:

I. Physiological Causes

This may be due to factors such as intense physical activity or overexertion. The condition typically resolves spontaneously with rest and usually does not require special treatment.

II. Pathological Causes

1. Pyelonephritis

Pyelonephritis may be caused by infection of the kidneys by pathogens such as bacteria, fungi, or viruses. Inflammatory factors stimulate body tissues, leading to symptoms such as loss of appetite, nausea, and painful urination. Routine urinalysis may reveal the presence of hematuria (blood in the urine). Patients can take medications such as minocycline hydrochloride capsules or cefixime granules under medical guidance.

2. Renal Cyst

Renal cysts may be related to genetic or environmental factors and can cause symptoms such as pain in the waist and abdomen or a palpable mass, often presenting as intermittent distending pain in the flank or back. Urinalysis may show red blood cells. Treatment options include percutaneous cyst sclerotherapy, traditional open surgery, or laparoscopic surgery.

In addition to the above common causes, other potential diseases such as urinary tract tumors should also be considered. It is recommended to seek timely diagnosis and appropriate treatment. Patients are encouraged to engage in regular physical activities such as brisk walking, tai chi, or badminton to enhance immunity.
