Nechiporenko urine test
A counted urine sediment: leukocytes, erythrocytes, and casts per milliliter of midstream urine. Clarifies a borderline general urinalysis.
Other names: Nechiporenko test, urine sediment per milliliterSection: Urine tests
Updated: August 31, 2026·MedProtect editorial team Reference information — not a diagnosis or a prescription
In shortThe Nechiporenko test counts cells and casts in 1 mL of midstream morning urine. Typical normal values are up to 2000 leukocytes/mL, up to 1000 erythrocytes/mL, and up to 20 casts/mL. It refines a questionable general urinalysis and helps monitor urinary tract inflammation.

What this marker is
Unlike the general urinalysis, which reports cells per microscope field, this test counts formed elements per milliliter — a more standardized measure of how many blood cells the urinary tract is shedding.
It is ordered when a routine urinalysis is borderline, when cystitis or pyelonephritis is suspected, and to follow treatment of urinary tract inflammation.
When it is high
Urinary tract infectionLeukocyturia with bacteriuria is the typical picture of cystitis or pyelonephritis.
Glomerular diseaseErythrocytes with casts point toward the kidney filter rather than the lower tract.
Stones and other causesCalculi, tumors, and instrumentation can shed erythrocytes.
When it is low
Expected findingLow counts mean no significant cellular shedding.
What can skew the result
These factors can shift the value without any disease — worth considering before a retest:
MenstruationCollection technique (midstream matters)Vigorous exercise the day before
How to prepare
Midstream portion of the first morning urine after hygiene of the external genitalia, in a clean container; delivered to the laboratory within 1–2 hours.
When a retest makes sense
An elevated count is repeated with correct collection; further steps are decided by the doctor.
Who usually reviews this result
A result outside the reference range is usually reviewed by: your GP or primary care doctor; a urologist or nephrologist for persistent abnormalities. Bring your lab report and any previous results to the appointment.
