What is the full name of "ELISA"

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2024

Explanation

ELISA stands for Enzyme-Linked Immunosorbent Assay.
The name describes the key components of the test: an enzyme is linked to an antibody (Enzyme-Linked).
The test is based on the principles of immunology, specifically antigen-antibody binding (Immuno).
One of the components is adsorbed or bound to a solid phase (Sorbent).
An assay is a procedure for analyzing a substance.

Option A: This option incorrectly uses 'licensed' and 'solution activity'. The correct terms are 'linked' and 'sorbent assay'.
Option C: This option incorrectly uses 'integrated' and 'solution activity'. The correct terms are 'immuno' and 'sorbent assay'.
Option D: This option is close but incorrectly uses 'solution assay' instead of 'sorbent assay'. The 'sorbent' part is crucial as it refers to the binding of components to a solid surface, which is a key feature of the technique.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Full form and principle of ELISA (Enzyme-Linked Immunosorbent Assay) as background academic context rather than a clinical decision trigger.
ELISA is a fundamental diagnostic tool in nursing and medicine for detecting a wide range of conditions, including infectious diseases (e.g., HIV, Hepatitis B/C), autoimmune disorders, and hormonal imbalances.
Nurses may be responsible for collecting samples (blood, urine) for ELISA testing and interpreting the results in the context of a patient's clinical picture.
Understanding the principle of ELISA helps in appreciating the sensitivity and specificity of the test and why it is a gold standard for many diagnoses, such as screening donated blood for infectious agents.

How to Approach the Question

First, identify the core of the question, which is to find the full form of the acronym 'ELISA'.
Break down the acronym based on your knowledge of medical terminology. 'E' likely stands for Enzyme, 'I' for Immuno.
Analyze the options by comparing them part-by-part. Notice the common words 'Enzyme linked' and 'immune'.
Focus on the differentiating words: 'licensed' vs. 'linked', 'sorbent' vs. 'solution' vs. 'integrated'.
Recall or deduce that 'sorbent' refers to the absorption/binding process on the test plate, which is a key feature of this assay. This points towards 'immunosorbent'.
Eliminate options with incorrect or less plausible terms like 'licensed', 'integrated', or 'solution', leading you to the correct full name.
