Definition

Hematuria is a fancy medical term for "blood in the urine".

Additional Info

Hematuria falls into two general classes:

1. Gross hematuria means that the blood can be seen in the urine with the naked eye. This condition is usually the result of internal bleeding, usually from the kidneys or bladder. Possible causes include accident, trauma or disease. Seek medical attention immediately.
2. Microscopic hematuria is a degree of bleeding so low that the blood can not be seen with the naked eye. Possible causes include kidney or bladder disease or damage. This condition can be detected through laboratory tests.

SDS Relevance

Finding blood in your urine is not normal. Seek medical attention if you suspect you have blood in your urine.

Exposure to certain chemicals can cause hematuria. One example is acetic acid.

When this term is found on Safety Data Sheets it is usually in Section 11 (toxicological information) as a symptom of exposure. Other sections of the SDS should explain how you can take appropriate precautions to reduce your risk of exposure.
