CALIBRATION is the process of evaluating and adjusting the precision and accuracy of measurement equipment. Proper calibration of an instrument allows people to have a safe working environment and produce valid data for future reference
The main reasons for calibration are to ensure the reliability of the instrument, that it can be trusted. To determine the accuracy of the instrument and to ensure the readings are consistent with other measurements. Considering the costs arising from legal action for damages that might be filed, the expenses for proper calibration and adjustment are minor in comparison. A measurement error is the difference between a measured value of quantity and its true value. errors tend to become more frequent the longer a device is in Such operation. At some time, the deviations might be so great that they are no longer within the specifications, which means that quality is no longer assured. By calibrating the device, the measurement error can be determined and documented. If the measurements are outside the permissible range, the device needs to be adjusted. In this process, the measuring instrument is reconfigured so that measurement errors are minimized and deviations from the set point value are within the device specifications.
There are two situations that account for hazards from electric shocks, viz. (i) gross shock and (ii) micro- current shock. The gross or macro shock is the high value current passing through the body due to faulty plug, socket, power chord etc. This can happen to all and can be easily identified. The other type is shock due to micro currents. This happens due to leakage currents inside the instruments caused by the leakage current generated within the instrument due to parametric changes within the components, low quality of materials used, poorly insulated windings and incorrect designs etc. The effects of these currents on the patient’s body result in life-threatening situations like ventricular fibrillation. It is the most common cause of death by electrocution in hospitals.
Malfunction is usually caused by a breakdown of the control systems in a machine or equipment. The malfunctioning of the biomedical instruments or parametric changes of components may cause variations/ fluctuations in the micro-current, leading to the fatal consequences.
To avoid these fatal consequences due to faulty instruments, it should be made mandatory that all such instruments that come in contact with the human body during the healthcare process, should be tested and calibrated periodically.

Accreditation is the formal recognition, authorization and registration of a laboratory that has demonstrated its capability, competence and credibility to carry out the tasks it is claiming to be able to do. The concept of laboratory accreditation was developed to provide third-party certification that a laboratory is competent to perform the specific test or type of tests. Laboratory accreditation is a means to improve customer confidence in the test reports issued by the laboratory so that the clinicians and through them the patients shall accept the reports with confidence.
The National Accreditation Board for Testing and Calibration Laboratories (NABL) is an autonomous body under the aegis of the Dept. of Science & Technology, Govt. of India, and is registered under the Societies Act. NABL, which was initially established with the objective to provide accreditation to testing & calibration laboratories, later on extended its services to the clinical laboratories in our country. Our scope of NABL accreditation is for MICROPIPETTES, PRECISION BALANCES, CALIBRATION OF E1, E2, F1, F2 CLASSES OF WEIGHTS, GLASSWARE
