A Look at How Metrology is Used to Improve the Healthcare Industry

Metrology is the science of measurement involving experimental and theoretical determination in both the scientific and technology sectors. Metrology is essential for different sectors including assessable variables, measurements, estimates and tools. The applications are appropriate for many areas such as medicine.

Metrology Categories

The three metrology categories are industrial, scientific and legal. Legal metrology is measurements influenced by economic transactions. Materials are purchased and sold for economic studies as opposed to physical tools. The focus of scientific metrology is to develop measurement maintenance and standards such as research and new technology for healthcare, government and commercial products.

Industrial metrology makes certain instruments for different sectors operating properly including medical machines, aircraft designs, manufacturing of commercial products and rotating equipment necessary for factories. Metrology is important for the medical sector as defined below.

Recognizing Measurements Globally

The use of medical devices has enabled measurements to achieve global recognition and standards of precision. Metrology is responsible for the global and national recognition of standards. Precision is achieved in the medical field through calibration and verification processes.

The accuracy standard of calibration defines less precise measurements for instruments in the medical field. Globally recognized measurements are important for health assessments for the population of the world and offer valuable data.

Data Evaluation

Metrology and inspection are essential for conformance control. Examination ensures the level of compliance is correct, deficiencies are detected prior to further production and quality requirements are attained. Metrology provides both practical and theoretical accuracy for measurements. Performance decisions are dependent on inspection and measurement.

If the tasks are performed incorrectly, the result is often undesirable. Poor test evaluations and incorrect analysis in the medical field can have serious consequences. The outcomes of clinical studies can be interpreted correctly by understanding limitations and metrological concepts.

Minimizing Rejects

Metrology involves the use of statistics for quality control to decrease rejects and retesting. This minimizes the time necessary for tests to be conducted by medical practitioners while ensuring the results are accurate. Costs are also decreased to ensure quicker diagnosis and improve the efficiency of hospitals.

Measuring Instrument Reliability

Accuracy rates for measuring instruments have improved due to microelectronics. The requirement for additional accuracy, speed and flexibility have been met with modern measuring techniques. Metrology is now essential due to the increase in microtechnology and nanotechnology to ensure high efficiency for measuring techniques.

Conformity Assessments

Measuring devices are required by healthcare for the prevention, diagnosis and treatment of diseases. These instruments are extremely important for the prioritization of safety and accuracy for patients. Healthcare systems are required to follow international guidelines for conformity assessments to ensure medical devices are reliable. Unfortunately, these guidelines have not yet been adopted by certain nations. Not only is implementation essential, but it also requires legal metrology.


Metrology offers substantial protection for the population by determining the correct measurement for radiation and dosage. It is also essential for food and road safety. Without metrology, methodologies and healthcare procedures would come to a standstill. An established method is necessary for every medical measurement from simple to complex. These standards are unachievable without metrology including blood pressure, X-rays and temperature.
