Non-specific Background Signal Too High in Competitive ELISA

High background optical density is observed across wells, reducing signal-to-noise ratio and making it difficult to distinguish specific binding from non-specific interactions.

Non-specific Secondary Antibody Binding Causing High Background

Elevated background signal across wells, including negative controls. Signal appears uniformly high rather than specific to target-containing wells.
