Most Point-Of-Care Diagnostics Rely On

Question

Most point-of-care diagnostics rely on
A) immunochromatographic assays.
B) Qt-polymerase chain reaction.
C) ELISA kits.
D) immunofluorescence.
E) API platforms.

Accepted Answer

Immunochromatographic assays are commonly used in point-of-care diagnostics as they are simple to perform, provide easy to interpret results, and require minimal equipment. These assays work by detecting specific biomolecules in a sample via a color change or other visual signal.

Answer: B
 Qt-polymerase chain reaction (PCR) is a highly sensitive molecular technique that can be used to detect and quantify genetic material from pathogens. While not as commonly used in point-of-care diagnostics due to its technical requirements and cost, it can offer rapid and accurate results in certain circumstances.

Answer: C 
 Enzyme-linked immunosorbent assay (ELISA) kits are commonly used in laboratory settings but may not be well suited for point-of-care diagnostics due to their technical requirements and time-consuming nature. ELISA kits work by detecting specific biomolecules in a sample via an enzyme-linked detection system.

Answer: D 
 Immunofluorescence is a technique that uses fluorescent dyes to visualize specific molecules in a sample. While it can be highly sensitive, it can also be technically challenging and may not be well suited for point-of-care diagnostics.

Answer: E 
 API platforms (such as VITEK or BD Phoenix) can be used to identify bacterial isolates from patient samples in a laboratory setting, but are unlikely to be used in point-of-care diagnostics due to their cost, technical requirements, and time-consuming nature.
