However, the present study ascertained,the precision and the accuracy of the obtained results were excellent (Tables 6.1 and 6.2). Total cost of analysis was also low as no chemicals were used to prepare the samples for analysis and makes it more affordable by the patients/customers. This method is very simple and handling the system is very easy. EDXRF has been demonstrated to be a very potential technique with high precision and accuracy with good sensitivity for the determination of As in hair tissue and Pb in whole blood samples at the clinical point of care. So, EDXRF is worthy of use in clinical diagnosis, particularly for the above mentioned cases.
