Adequately calibrated equipment can boost efficiency by lowering the need for repeat tests. It saves waste and prevents the expense of rework due to unwanted errors.
Further, calibration involves comparing the readings of medical equipment to a known standard or reference and making adjustments as necessary to ensure that the equipment is accurate. So, calibrated instruments enable medical personnel to make a better-informed diagnosis. Also, it treats patients more successfully by maintaining precise and accurate measurements.
Additionally, one may ask about the importance of calibration in laboratory equipment for measurement? So, the answer is simple. It’s critical to calibrate medical equipment used in diagnostics to ensure it operates precisely and consistently. Measurements must be accurate for diagnostic devices like blood glucose meters, blood pressure monitors, and ECG machines, to produce reliable results. On the other hand, Non-calibration can lead to inaccurate measurements and potentially incorrect diagnosis and treatment.
2. Lab Equipment Calibration Procedure
Medical Lab equipment calibration is a crucial procedure that tries to lower measurement uncertainties, minimize errors, and improve measurements to an acceptable level. Medical equipment tends to deteriorate with usage, harming its accuracy and precision. Hence, routine calibration of lab equipment is necessary to guarantee that the machinery operates at peak efficiency while retaining precision and dependability.
Clinicians and lab technicians are well aware of the concept of calibration. An essential aspect that can optimize calibration policies is setting up a proper lab equipment calibration procedure. Thus, a comprehensive plan encompassing all activities, procedures, and compliances can become a task.
Here is a 5-step plan for setting up a calibration process in a medical laboratoty:
I. Identify the equipment:
The first step is to identify all the medical diagnostic equipment that needs calibration instructions. The list may include instruments for diagnostic testing, such as blood glucose meters, blood pressure monitors, ECG machines, analyzers, etc.
II. Determine the calibration frequency:
After identifying the equipment, ascertain how frequently it needs calibration. Based on the manufacturer’s recommendations, legal regulations, or internal policies of the facility.
III. Develop calibration procedures:
Moving ahead, create written calibration protocols. The procedure should outline the precise procedures to calibrate each piece of equipment and the required instruments and reference standards.
IV. Train staff:
Further, staff members should receive training on calibrating methods and be made aware of the necessary tools and equipment. Make sure the team knows the value of calibration and how incorrect readings can affect patient care.
V. Document calibration results:
Keep a record of the calibration results and calibration instructions for each piece of equipment. Using laboratory equipment management software can help you record everything including the calibration date and name of the technician who carried out the calibration. The calibration outcomes should all be in this record. Document any modifications that were made during the lab equipment calibration procedure.
Some of the standard documentation a lab must maintain are as follows:
-
- Monthly, quarterly, and yearly calibration schedule
- Calibrations SOP or steps in the calibration
- Calibration results datasheet
- Error measurement of the equipment
- Updated Instructions Manual or user manuals.
