Understand your values of Erythrocytes in Urine (/µl)

What is it and its measure units?

Erythrocytes in urine, commonly known as red blood cells, are the cells that carry oxygen from the lungs to the rest of the body and return carbon dioxide for exhalation. The presence of erythrocytes in urine is a measure typically expressed in cells per microliter (µl). Normally, urine should contain very few or no erythrocytes, as they primarily circulate within the bloodstream. Although it is common to have trace amounts, higher counts can indicate various health conditions, making it an important marker to monitor through routine urinalysis.

Which is its function in our bodies?

Erythrocytes play a crucial role in the body’s respiratory system. Their primary function is to transport oxygen from the lungs to the body's tissues and return carbon dioxide back to the lungs for exhalation. This process is facilitated by a protein called hemoglobin, which resides within red blood cells and has a high affinity for oxygen. In the context of a urinalysis, erythrocytes should ideally not be present in large amounts in urine, as they serve vital functions within the blood itself. Their presence in urine may suggest an underlying issue, as typically, they do not pass through the kidneys into the urinary tract unless there is a problem.

What happens if we have values out of normal?

When the level of erythrocytes in urine goes beyond normal, it can be a signal of various health issues. Hematuria, which refers to the presence of blood in urine, can occur due to urinary tract infections (UTIs), kidney disease, kidney stones, a result of trauma, or even cancer. Infections and inflammation of the bladder, kidneys, or urethra can cause erythrocytes to leak into the urinary system. While a minor increase may suggest a benign issue such as vigorous exercise, significant increase often warrants further investigation. If you suspect abnormal levels of red blood cells in your urine, it is critical to seek medical advice promptly to determine the underlying cause and necessary treatment.

Which are its optimum values and what should we do to improve our values of this substance?

Ideally, urine should contain zero to a few erythrocytes per microliter. Anything higher may necessitate further clinical testing to confirm an underlying condition. To help ensure erythrocyte levels in urine remain within normal range, maintaining good hydration is crucial, as it aids kidney function and the body's filtration processes. Implementing a healthy diet rich in fruits and vegetables can also enhance overall kidney health. Additionally, avoiding risky activities that can lead to urinary tract infections or trauma can prevent blood from entering the urine. If advised by a healthcare professional, regular screening can be an effective preventative measure.
