Keywords: ECP

Specimen:

5 mL blood in a plain tube.

Broncho-alveolar lavage fluid.

Method:

Immunoassay.

Reference Interval:

Application:

Useful in monitoring childhood asthma where peak flow measurement is impossible.

Interpretation:

Raised levels indicate increased in vivo eosinophil activity.

Levels have been reported to correlate with clinical severity of asthma and with decreased peak flow rates.
