Treatment and study plan

Serum biomarker testing

Diagnostic Test

Serum and sputum samples will be collected and biomarkers will be evaluated using ELISA

Primary outcomes

  1. Serum calprotectin

    Time frame: Day 1

    Serum Calprotectin (pg/ml) will be measured in serum samples using a U-plex assay

Secondary outcomes

  1. Sputum calprotectin

    Time frame: Day 1

    Sputum Calprotectin (pg/ml) will be measured in sputum samples using a U-plex assay
