The Importance of Diagnostic Testing

The Importance of Diagnostic Testing

Healthcare starts with and depends on diagnostics, whether it’s cancer, diabetes, infectious diseases or serious health threats, diagnostics are at the front and centre. Diagnostics enable physicians and clinicians to gather the precise information to aid in the early detection, prevention and monitoring of diseases. Moreover, diagnostics are vital in optimising care pathways and in the creation and implementation of treatment plans. Despite this, diagnostics are greatly undervalued with many healthcare systems around the world sorely lacking in awareness of the importance of and capacity to integrate diagnostics 1.


The Role of Diagnostic Tests

Diagnostic tests are used routinely in clinical practice. They can be non-specific (complete blood count) and specific (Anti-CCP for rheumatoid arthritis). Diagnostic tests are utilised for three key reasons 2:


Upon evaluating a patient, including a physical exam and reviewal of symptoms, a clinician will order diagnostic tests to confirm a suspected condition or to exclude conditions. Of course, the early detection of a disease, with the help of diagnostic tests, can help your clinician implement treatment plans swiftly, and halt the progression of disease 2.


Following a diagnosis, further diagnostic tests can be requested to determine if the treatment is working effectively 2.


Diagnostic testing can aid a doctor in reviewing the progression of disease and predict how long one will live 2.


The Role of Diagnostic Tools

Diagnostic testing is a crucial aspect of clinical practice, however, it is fundamental that every diagnostic test has a suitable degree of reliability and validity. If these two crucial requirements are not met, the usefulness of the test in supporting a physician’s diagnosis, developing a treatment plan, or monitoring the progress of a patient becomes an issue 3.

Along with the diagnostics tests, doctors also employ diagnostic medical equipment to assess and monitor several aspects of a patients’ health. Diagnostic analysers are utilised to run diagnostic tests, which is essential for a variety of measurements, including: hepatic function, immunological markers and antibodies, renal function etc 3.


The Importance of Diagnostics

Diagnostics is important because it can help patients live longer and healthier lives when disease progression is delayed or halted, or patients recover through early and timely diagnosis, followed by the early implementation of treatment plans. Moreover, diagnostics provide information that can greatly benefit the patient as healthcare professionals can choose the appropriate preventative interventions as well as providing vital prognostic data that allows for the optimisation of care pathways and management. Diagnostic data can also aid in reducing, shortening and avoiding hospitalisation, decrease inappropriate medication use, and shorten the length of or prevent sick leave. As such, diagnostics brings economic value in terms of cost-containment and fostering improved health outcomes, and ultimately enabling the efficient use of resources 4.
