Yes, 100 WBC (White Blood Cells) in urine is considered high.
According to reference material, levels above 10 WBC/HPF (per high power field) in urine suggest inflammation. A count of 100 WBC/HPF is significantly higher than this threshold, strongly indicating a potential issue. This elevated level often points towards a:
- Bacterial infection
However, inflammation can be caused by other factors as well.
Factors Contributing to Elevated WBC in Urine
While a high WBC count often indicates a bacterial infection, other causes can contribute:
- Urinary Tract Infection (UTI): This is the most common cause. Bacteria enter the urinary tract and cause inflammation.
- Kidney Infection (Pyelonephritis): A more serious infection that can result in a very high WBC count.
- Bladder Inflammation: Conditions like interstitial cystitis can inflame the bladder lining.
- Kidney Stones: Irritation from kidney stones can lead to inflammation and increased WBCs.
- Certain Medications: Some drugs can cause inflammation in the urinary tract.
Diagnosis and Next Steps
A high WBC count in urine warrants further investigation. Your doctor will likely:
- Review your symptoms: This helps to narrow down the potential causes.
- Order additional tests: A urine culture can identify the specific bacteria causing an infection. Other tests, like imaging, might be necessary.
- Consider bacteria and nitrite presence: The reference highlights that presence of bacteria and/or nitrites (by-product of certain bacteria) could indicate a bacterial infection.
Understanding Your Results:
Here's a table summarizing what different WBC levels might indicate:
| WBC Count (per HPF) | Interpretation | Possible Action |
|---|---|---|
| 0-10 | Normal range | None needed |
| 10-20 | Mild elevation, possible inflammation | Further testing might be needed |
| 20-100 | Moderate elevation, likely infection or inflammation | Further testing and possible treatment may be needed |
| Over 100 | Significant elevation, likely infection | Further testing and immediate treatment likely needed |
