Clinical Application Of POCT

Jan 17, 2018

With the use of various POCT technologies and instrumentation, POCT can be implemented both inside and outside the hospital. Some special items can be detected even at home or on special occasions (eg outdoors, on site), greatly facilitating the needs of patients and special populations.

(1) diagnosis and treatment of diabetes applications

A variety of rapid blood glucose meter, a variety of non-invasive blood glucose detector makes the report time (TAT) greatly reduced, clinical, patients and families the most commonly used detection equipment; quantitative immunofluorescence detection of diabetic patients glycosylated hemoglobin and urine Trace albumin and other indicators help to early detection of diabetic nephropathy is conducive to the assessment of the patient's condition and long-term monitoring; sensor-related detector can detect blood gas and electrolytes and other indicators; dry chemical analyzer can detect the patient's blood in a variety of biochemical indicators .

(2) the application of cardiovascular disease

Acute Myocardial Infarction (AMI) the incidence of acute and seriously affect the patient's life safety. The use of POCT AMI patients can be timely diagnosis and treatment. Gold standard quantitative detector, full quantitative immunofluorescence detector, rapid CRP detector and other detectable specific serum early markers such as troponin I (cTnI), myoglobin (Mb), creatine kinase MB CK-MB), D-dimer, BNP and CRP. The prothrombin time (PT) was measured by dry-plate type hemagglutination analyzer. The activated partial thromboplastin time (APTT) Chemical analyzer can detect blood aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase (CK) and other biochemical indicators of detection; sensor-related analyzer can detect blood gas and electrolytes and other indicators .

(3) the application of infectious diseases

Diagnostic protein chip technology, immunogold labeling technology related POCT use, can not have the bacterial culture conditions of grassroots hospitals, private clinics, community health centers for rapid detection of microorganisms, but also can be used in hospitals in pre-operative infectious disease four tests ( HBsAg, HCV, HIV, TP), screening of viral hepatitis before endoscopy and so on.

(4) the application of fever diseases

The use of a rapid CRP detector, combined with the results of CRP and blood tests, is more specific than the single test in identifying the nature of the infectious agent (bacteria or virus) that infects patients with fever.

(5) ICU ward application

In the ICU ward, currently used clinically are: electrochemical sensors for in vitro monitoring, which can periodically control the patient's blood gas, electrolytes, hematocrit and blood glucose; biosensors for in vivo monitoring, Installed in the probe or catheter wall, placed in the artery or vein lumen, through the monitor can be regularly measured data to be measured.

(6) Pediatric diagnosis and treatment of applications

Suitable for children's diagnostic behavior need to light, easy to use, non-invasive or traumatic small sample less, without pretreatment, rapid conclusion and other factors to shorten the treatment cycle, but also need to pay attention to the satisfaction of parents. POCT can better meet the above requirements. Another characteristic of POCT is that parents can always stay with their children when diagnosing their illness and keep abreast of the meaning of the test data to better communicate with the medical staff and facilitate the diagnosis and treatment of children's diseases.

(7) Evidence-based medicine

From the perspective of evidence-based medicine, POCT makes up for the cumbersome problems of traditional clinical laboratory processes. Evidence based medicine (EBM) is evidence that follows the best medical research in modern times and applies the evidence to the clinical decision-making process of scientific diagnosis and treatment of patients. The experimental instruments used in POCT are small, portable, and easy to use, and operators can do it anywhere in the lab to quickly and easily retrieve some patient-specific data that is the primary purpose of evidence-based medicine - Followed by.

(8) Hospital outside the application

POCT instruments related to various immunogold techniques, POCT instruments related to sensor technologies, and POCT instruments related to dry chemical techniques are widely used in family self-care, community health care, physician's office, infirmary, medical examination center, Ambulances, the scene of the accident (and even the battlefield), exit and entry quarantine, anti-drug, drug treatment centers, public security departments and athletes urine testing many departments and places outside the hospital widely used.
