Fluoride Quantitative, Serum or Plasma
Also known as: FLUORIDE
Use
This test measures fluoride levels in serum or plasma, typically used for assessing fluoride exposure or monitoring treatment efficacy. Fluoride levels may be affected by water fluoridation and consumption, thus, reference ranges are adjusted accordingly. Clinical decisions based on this test should consider potential environmental contamination during specimen collection.
Special Instructions
This test requires separate specimens if multiple tests are ordered, as it is not performed at ARUP Laboratories.
Limitations
Elevated results may be due to environmental contamination during collection. It is recommended to verify unexpected elevated results by testing another specimen in a trace metal-free container. This test is performed by NMS Labs and has not been FDA-cleared or approved.
