10-15/hpf rbc in urine means

Red blood cells (RBCs), also known as erythrocytes, deliver oxygen to the tissues in your body and release carbon dioxide into your lungs to exhale. The presence of RBCs in the urine, which is medically termed hematuria, is not normal and can be a sign of an underlying health condition.

What does hpf mean?

HPF, or “High Power Field” refers to the field of view under the maximum magnification power of the objective being used. In fact, each microscope has two types of lenses; the objective, and the eyepiece. The magnification power of the microscope can be calculated by multiplying the magnification power of the eyepiece by the magnification power of the objective lens.

So if an objective lens with a magnification of 10x is used with a 40x magnification eyepiece lens, it will display the sample image 400 times larger, abbreviated as hpf (1).

10-15/hpf rbc in urine means

According to what we explained above, 10-15/hpf rbc in urine means that 10-15 red blood cells were found in your urine at 400x magnification. The presence of this amount of RBCs in urine is not normal and can be due to glomerular or non-glomerular causes.

Some common glomerular causes are:

· Alport syndrome

· Thin basement membrane disease

· Types of glomerulonephritis

· nephropathy

· Lupus nephritis

· Goodpasture syndrome

· Nephrotic syndrome

· Polycystic kidney disease

Non-glomerular causes include:

· Febrile illness

· Exercise

· Menstruation

· Nephrolithiasis

· Cystitis, urethritis, prostatitis

· Malignancy: renal cell carcinoma, bladder cancer, prostate cancer

· Genitourinary mucosal injury by instrumentation

· Trauma

· Bleeding tendency: thrombocytopenia, coagulopathy, use of blood thinners, hematological disorders like sickle cell anemia (2)

If your test result is “10-15/hpf rbc”, you may need further tests to figure out what is causing it.
