Point-of-care testing (POCT), or bedside testing is defined as medical diagnostic testing at or near the point of care—that is, at the time and place of patient care.[1] This contrasts with the historical pattern in which testing was wholly or mostly confined to the medical laboratory, which entailed sending off specimens away from the point of care and then waiting hours or days to learn the results, during which time care must continue without the desired information.
Point-of-care tests are simple medical tests that can be performed at the bedside. In many cases the simplicity was not achievable until technology developed not only to make a test possible at all but then also to mask its complexity. For example, various kinds of urine test strips have been available for decades, but portable ultrasonography did not reach the stage of being advanced, affordable, and widespread until the 2000s and 2010s. Today portable US is often viewed as a "simple" test, but there was nothing simple about it until the more complex technology was available. Similarly, pulse oximetry can test arterial oxygen saturation in a quick, simple, noninvasive, affordable way today, but in earlier eras this required an intraarterial needle puncture and a laboratory test; and rapid diagnostic tests such as malaria antigen detection tests rely on a state of the art in immunology that did not exist until recent decades. Thus, over decades, testing continues to move toward the point of care more than it formerly had been. A recent survey in five countries (Australia, Belgium, the Netherlands, the UK and the US) indicates that general practitioners / family doctors would like to use more POCTs.
The driving notion behind POCT is to bring the test conveniently and immediately to the patient. This increases the likelihood that the patient, physician, and care team will receive the results quicker, which allows for better immediate clinical management decisions to be made. POCT includes: blood glucose testing, blood gas and electrolytes analysis, rapid coagulation testing (PT/INR, Alere, Microvisk Ltd), rapid cardiac markers diagnostics (TRIAGE, Alere), drugs of abuse screening, urine strips testing, pregnancy testing, fecal occult blood analysis, food pathogens screening, hemoglobin diagnostics (HemoCue), infectious disease testing and cholesterol screening.
POCT is often accomplished through the use of transportable, portable, and handheld instruments (e.g., blood glucose meter, nerve conduction study device) and test kits (e.g., CRP, HBA1C, Homocystein, HIV salivary assay, etc.). Small bench analyzers or fixed equipment can also be used when a handheld device is not available—the goal is to collect the specimen and obtain the results in a very short period of time at or near the location of the patient so that the treatment plan can be adjusted as necessary before the patient leaves. Cheaper, faster, and smarter POCT devices have increased the use of POCT approaches by making it cost-effective for many diseases, such as diabetes, carpal tunnel syndrome (CTS) and acute coronary syndrome. Additionally, it is very desirable to measure various analytes simultaneously in the same specimen, allowing a rapid, low-cost, and reliable quantification. Therefore, multiplexed point-of-care testing (xPOCT) has become more important for medical diagnostics in the last decade.

MSLRDT004 HBsAg Rapid Test Dipstick for Sale

The  HBsAg  Rapid  Test Dipstick  is  a  rapid  chromatographic  immunoassay for  the  qualitative detection of Hepatitis B Surface Antigen in whole blood, serum or plasma.

Viral hepatitis is a systemic disease primarily involving the liver. Most cases of acute viral hepatitis

are caused by Hepatitis A virus, Hepatitis B virus (HBV) or Hepatitis C virus. The complex antigen

found on the surface of HBV  is called HBsAg. Previous designations included the Australia or  Au

antigen. The  presence of HBsAg  in whole  blood, serum or  plasma is  an indication  of an active

Hepatitis  B infection,  either acute  or  chronic. In  a  typical Hepatitis  B  infection, HBsAg  will  be

detected 2 to 4 weeks before the ALT level becomes abnormal and 3 to 5 weeks before symptoms

or  jaundice develop.  HBsAg  has  four principal  subtypes:  adw, ayw,  adr  and  ayr. Because  of

antigenic heterogeneity of the determinant, there are 10 major serotypes of Hepatitis B virus.

The HBsAg  Rapid Test  Dipstick is a  rapid test  to qualitatively detect  the presence  of HBsAg  in

whole  blood, serum  or  plasma  specimen.  The test  utilizes  a  combination  of monoclonal  and

polyclonal  antibodies to  selectively  detect elevated  levels of  HBsAg  in whole  blood,  serum or


MSLRDT004 HBsAg Rapid Test Dipstick for Sale

The HBsAg Rapid Test  Dipstick is a qualitative, solid  phase, two-site sandwich immunoassay for

the  detection of  HBsAg  in  whole blood,  serum  or plasma.  The  membrane  is pre-coated  with

anti-HBsAg antibodies  on  the test  line  region of  the Dipstick.  During  testing, the  whole blood,

serum  or  plasma  specimen  reacts  with  the  particle  coated with  anti-HBsAg  antibodies.  The

mixture migrates upward  on the membrane  chromatographically by capillary  action to react with

anti-HBsAg  antibodies  on  the membrane  and  generate  a  colored  line.  The  presence of  this

colored line  in the test  region indicates  a positive result,  while its  absence indicates a  negative

result. To serve as a procedural control, a colored line will always appear in the control line region

indicating that proper volume of specimen has been added and membrane wicking has occurred.


The test Dipstick contains anti-HBsAg particles and anti-HBsAg coated on the membrane.
