Blood concentrations of essential trace elements can be used to diagnose conditions and diseases associated with excess or deficiency these elements. Inductively coupled plasma mass spectrometry (ICP-MS), inductively atomic emission spectroscopy (ICP-AES), graphite furnace absorption (GF-AAS) have been employed for such measurements, but maintenance operation costs are high. X-ray fluorescence (XRF) detectability in cutaneous blood iron (Fe), copper (Cu), zinc (Zn), selenium (Se) was assessed as an alternative ICP-MS. Three phantoms were made up two polyoxymethylene (POM) plastic cylindrical cups 0.6 mm 1.0 thick walls a 5.3 diameter POM insert. Six aqueous solutions Fe 0 500 mg/L Cu, Zn, Se 50 poured into the simulate attenuation skin. Measurements using integrated tube polycapillary lens unit generated 24 calibration lines. Detection limit intervals (36–100), (14–40), (3.7–10), (2.1–3.4) Fe, Se, respectively. only element detection limits lower than its 480 median human concentration. The estimated radiation dose equivalent skin below those common radiological procedures. Applications will require further instrumental development finding method.
