Definition, Benefits, and Drawbacks of Point Of Care Testing (POCT)


Providers of healthcare seek to practice medicine as quickly as possible while attaining the best possible outcome. Quick and accurate test results can help a health care provider provide the best possible care to their patients by allowing them to make more informed decisions.


Instead of sending a sample to a laboratory, point-of-care testing, also known as near-patient testing, involves performing a test with a gadget or test kit in the presence of the researcher. To keep care quality high, several cutting-edge point-of-care gadgets take use of technology advancements.


How does point-of-care testing operate, and what does it entail?


POC testing, or point-of-care screening, is healthcare testing performed at or near the point of care. In this programme, the sufferer’s location is considered to as pointclickcare cna login.
The results will take a long time to arrive if all traces and specimens are sent to medical laboratories for processing. As a result, vital time may be squandered, or patients may be managed without having every one of the knowledge their care team need.


Now that these data are available, medical providers may be able to make more informed decisions about a participant’s treatment and care.


Point-of-care vs. laboratory testing benefits and disadvantages:


The quickness with which a result may be acquired is the main advantage of point-of-care testing. The majority of data are presented in an easy-to-understand style, however this is not always the case, and the results may still need to be safely evaluated by a healthcare professional.
POC testing may be done by anybody who has not had professional laboratory training. Nurses, physicians, and medics are employed, as well as customer testing. Only a few instances of near-patient testing include malaria antigen scanning, pregnancy tests, glycaemic management, urinalysis, and other sorts of testing.


Simple samples of body fluids (such as saliva or urine) or blood through a finger prick are commonly required for these tests. POC testing, on the other hand, has some disadvantages. It may be used in conjunction with other portable medical equipment, such as thermometers or monitoring devices, to give a rapid and uncomplicated medical checkup.
Studies have shown that POC testing has a higher rate of mistakes than laboratory examination, based on the device’s current technology. Because the POC testing phase is less controlled than laboratory conditions, and the results are more sensitive to external interference than laboratory procedures, inaccuracies might arise.
Testing on-site has the possibility to be more expensive than testing in a lab. According to a 1995 research, the cost of POC glucose measurement was 1.1 to 4.6 times more than just the cost of almost the same test in the laboratories. Expenses such as those associated with a quality control programme or equipment maintenance are frequently overlooked. Other types of hidden expenses, such as equipment, workers, and overheads, may apply to tests performed.
Nonetheless, the convenience and speed of POC testing can compensate for the greater costs. Rapid discoveries enable for the implementation of a treatment plan quickly, which may make a big difference when time is of the importance for better care.


Simple samples of body fluids (such as saliva or urine) or blood through a finger prick are commonly required for these tests. They can be combined with other transportable medical devices, including as thermometers and pressure sensors, to provide a quick and painless medical evaluation.

Other types of hidden expenses, such as infrastructures, workers, and overheads, may apply to laboratory analysis.


Point-of-care haematology devices:

  1. Prothrombin time analysers are used to evaluate blood clots.
  2. aPTT testing is utilised for haemostatic assessment.
  3. D-dimer testing is done to rule out a blood clot or DVT.
  4. For trauma and obstetrics, a viscoelastic test was done.
  5. Activated partial thromboplastin time testing is used to assess heparin levels.
  6. Malaria antigen testing is performed to determine whether or not a person has the disease.
    The most extensively used and current point-of-care testing tools have been shown to provide accurate and reliable haematological results, leading in improved medical care for a range of disorders.
