Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
The correlation between the levels of mercury (Hg) excretion in the urine and the clinical symptoms is considered poor. However, urinary Hg is the most reliable way to assess exposure to inorganic Hg.
For more information, see HG / Mercury, Blood.
Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Method Description
Describes how the test is performed and provides a method-specific reference
Describes how the test is performed and provides a method-specific reference
Mercury (Hg) is analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) in MS/MS mode using oxygen as a reactive gas to mass shift tungsten away from the mass of interest. Internal standard used is iridium for Hg. A salt matrix calibration is used.(Unpublished Mayo method)

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
