Eosinophil Cationic Protein (ECP) Unit Converter
Eosinophil Cationic Protein (ECP) is a potent, cytotoxic protein released from the granules of eosinophils upon activation during inflammatory and allergic reactions. ECP acts as a neurotoxin and possesses ribonuclease activity, making it a critical mediator of tissue damage, particularly in the airways during asthma.
Clinically, serum ECP levels reflect the degree of eosinophil activation and systemic inflammation. It is often used to monitor the efficacy of anti-inflammatory treatment (such as inhaled corticosteroids) in asthma and to assess the severity of allergic rhinitis. High levels correlate with high eosinophil turnover and potential organ damage. This converter allows switching between the standard mass units and the SI molar unit.

Clinical Context
Reference Range: Serum ECP is normally very low, typically < 15ng/mL.
Levels > 25ng/mL are often associated with active asthma or severe allergy. ECP is a stable protein, making it an excellent marker of eosinophil activation. It often reflects tissue inflammation better than the absolute count of eosinophils in the blood. The conversion factor relies on MW 18.5 kDa: 1 ng/mL ≈ 54.05 pmol/L.

Frequently Asked Questions & Tips
Yes. $1 \text{ ng/mL}$ is exactly equal to $1 \mu\text{g/L}$.
It helps monitor the severity of eosinophilic inflammation, but it does not diagnose asthma itself.
