Yes, 50 red blood cells (RBCs) per high-power field (HPF) in urine is considered high. A normal range is generally considered to be up to 4 RBCs per HPF, although this can vary slightly depending on the laboratory. Finding 50 RBCs/HPF indicates the presence of high-grade hematuria, which requires further medical evaluation.
Understanding Hematuria
Hematuria refers to the presence of blood in the urine. It can be visible to the naked eye (gross hematuria), or only detectable under a microscope (microscopic hematuria). The presence of 50 RBCs/HPF falls under microscopic hematuria, but the high number warrants attention.
Several sources confirm that a significantly elevated RBC count in urine, such as 50 RBCs/HPF or higher, is not normal and may indicate an underlying medical condition. This warrants a consultation with a healthcare professional for proper diagnosis and treatment.
- National Practice Recommendations: Medical guidelines recommend referral to a urologist for patients with high-grade hematuria (>50 RBCs/HPF) on a single urinalysis. https://pubmed.ncbi.nlm.nih.gov/21373244/
- Potential Causes: While a urinary tract infection (UTI) can sometimes cause an increased number of RBCs in urine, a count as high as 50 RBCs/HPF necessitates investigation into other potential causes, which can include kidney stones, bladder cancer, or other kidney or urinary tract disorders. It's crucial to consult a doctor for a proper diagnosis.
