Arsenic/Creatinine Ratio details
What Arsenic/Creatinine Ratio shows
The arsenic/creatinine ratio is calculated from two measurements in a single urine sample: arsenic, a toxic element found in some groundwater, foods and industrial settings, and creatinine, a waste product your kidneys release at a fairly steady rate. Dividing one by the other corrects for how concentrated or dilute your urine is. Because most arsenic leaves the body within a few days, it reflects recent exposure. A higher ratio points to increased recent exposure. Fish and shellfish contain organic arsenic that is far less harmful but still raises the result, so seafood eaten in the days before testing can cause a high reading, and a high result is usually followed by testing that separates the arsenic forms.
Tests that include Arsenic/Creatinine Ratio
This panel evaluates and monitors exposure to heavy metals and detoxification status.
- Arsenic/Creatinine Ratio A ratio of arsenic to creatinine in a single urine sample, used to look for recent arsenic exposure while correcting for how dilute your urine is.
- Creatinine, Random Measures creatinine in a random urine sample, mainly used as a reference to adjust other urine results for how concentrated or dilute the sample is.
- Lead/Creatinine Ratio Lead in a random urine sample expressed relative to creatinine, which corrects for urine concentration, used to look at lead excretion and possible exposure.
- Mercury/Creatinine Ratio A random urine mercury result adjusted for creatinine, used to assess exposure mainly to elemental and inorganic mercury while correcting for urine dilution.
