C-1 ESTERASE ACTIVITY (INBITOR FUNCTIONAL ASSAY) )

When diagnosing C1 esterase inhibitor deficiency, also known as hereditary angioedema, or monitoring the response to therapy, assessing the C1 Esterase Inhibitor Quantitation serves as a crucial initial step. If the quantitation is found to be low, it is generally unnecessary to conduct a functional assay, as the functional activity is expected to parallel the quantitative levels. This streamlined approach not only simplifies the diagnostic process but also ensures efficiency by obviating the need for redundant testing when a deficiency in the C1 esterase inhibitor is evident. Such a strategy facilitates a more rapid and cost-effective assessment, allowing for timely interventions and tailored therapeutic strategies based on the identified deficiency in C1 esterase inhibitor levels.
