With an optimal cut-off of 51.21 ng\/mL, SP-A demonstrates a diagnostic sensitivity of 81.8% and specificity of 76.7% (AUC 0.858). Combining SP-A with other markers like KL-6, SP-D, and MMP-7 can further improve diagnostic accuracy. A recent meta-analysis of 2,573 interstitial lung disease (ILD) patients confirmed that elevated serum SP-A is a pivotal biomarker for assessing disease occurrence, progression, acute exacerbation, and mortality. Specifically, SP-A levels were significantly higher in progressive versus stable ILD, in acute exacerbation versus non-acute exacerbation, and in non-survivors versus survivors. In community-acquired pneumonia (CAP), lower serum SP-A on admission is associated with increased risks of mechanical ventilation, ICU admission, and poor prognosis. SP-A also shows diagnostic value in pulmonary alveolar proteinosis (PAP), tuberculosis, and as a marker for lung adenocarcinoma.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOverall, SP-A is a valuable diagnostic and prognostic biomarker, though standardization of assays and cut-off values remains a challenge for broader clinical translation.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Starter","offers":[{"title":"1mg","offer_id":67399913537611,"sku":"S0B3795-1mg","price":1170.0,"currency_code":"USD","in_stock":true},{"title":"0.5mg","offer_id":67399913570379,"sku":"S0B3795-0.5mg","price":670.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/1c4f505d6a31431f8ff9d9daeb9e6355.jpg?v=1793858536","url":"https:\/\/www.antbioinc.com\/products\/sp-a-recombinant-rabbit-mab-sdt-3520-21-s0b3795","provider":"AntBio","version":"1.0","type":"link"}
