23. Point-of-care testing is performed most easily using
A. homogeneous enzyme immunoassay.
B. immunofixation assay.
C. immunochromatographic assay.
D. capture ELISA.
Homework Answers
Point-of-care testing is performed most easily using the immunochromatographic assay.
Point of care testing means at the time of care, it's a diagnostic test that is done immediately at the time of patient care and it gives a result at that point of time.
the immunochromatographic assay is also known as strip test, Example - Pregnancy test kit
Answer - C. immunochromatographic assay.
