What is this test?

This test measures the amount of hexachlorophene in urine compared with the amount of creatinine. Creatinine is a waste product used to help account for how concentrated or dilute a urine sample is.

Why might I need this test?

The test may be ordered to evaluate exposure to hexachlorophene, which is used in some antiseptics, disinfectants, and industrial products. It may be considered for workers or others who could encounter this substance.

How is the test performed?

A urine sample is collected and tested in a laboratory to determine hexachlorophene and creatinine levels. The laboratory may report the result as a ratio or as both measurements with a calculated ratio.

How do I prepare for the test?

Follow any workplace or laboratory collection instructions, including avoiding unusual skin products shortly before collection if advised. The sample should be collected in the container provided and submitted within the recommended timeframe.

Frequently asked questions

What does hexachlorophene exposure mean?
It means that hexachlorophene may have entered the body through skin contact, inhalation, or ingestion. Exposure history and workplace safety measures help determine how the result should be interpreted.
Why is creatinine included in the result?
Urine can vary greatly in concentration. Dividing or adjusting the hexachlorophene result using creatinine helps reduce the effect of changes in urine concentration.
Does an abnormal result mean I am sick?
Not necessarily. An elevated result may show exposure, but symptoms and other clinical findings are needed to determine whether any health effects are present.
