The addition of a substrate produces a measurable signal, such as a color change, which correlates directly with the amount of target substance present. This technique is widely employed to screen for infectious diseases by identifying pathogens or the body's immune response to them.

Similarly, it plays a vital role in allergy testing by quantifying Immunoglobulin E (IgE) antibodies specific to allergens like pollen, dust mites, or certain foods, helping clinicians identify the triggers of allergic reactions. Detection of Autoimmune and Allergic Conditions Beyond infectious agents, what elisa detect also includes specific antibodies produced by the immune system in autoimmune disorders.
Interpreting Results and Limitations to Consider While the question of what elisa detect is straightforward, interpreting the results requires context. Furthermore, ELISA is instrumental in measuring hormone levels, such as those involved in pregnancy tests (hCG) or thyroid function, providing quantitative data essential for patient management.

This analytical method relies on the highly specific interaction between an antibody and its target antigen, making it a cornerstone tool in modern diagnostic medicine and biomedical research. The specificity of the antibody-antigen interaction minimizes false positives, provided the reagents and protocols are meticulously followed, ensuring reliable results for critical decision-making.
