The serum samples were analyzed for the determination of electrolytes and some trace elements such as calcium (Ca), sodium (Na) copper (Cu), lithium (Li), potassium (K) and iron (Fe) by using atomic absorption spectrophotometer (Nazifi et al., 2003) at Quality Operations Laboratory, UVAS, Lahore.
The calibration curves of six elements: As, Cd, Cr, Ni, Pb and Zn obtained by the instrument using the blank and four working standards 0, 10, 20, 40 and 100 g/L and for Al obtained by the instrument using the blank and three working standards 0, 100, 200 and 300 g/L for all elements, starting from a 1000 mg/L single standard solutions for ICP-MS (Aristar grade, BDH laboratory supplies, England for the trace elements. Correlation coefficient values for all elements were within the range from 0.998 to 0.999.
Interventions: 1-6 trace element measurements per patient.
