Not all lab files arrive in clean structured formats. The extractionMethod on an ImportBatch records whether data was read through a direct structured parse for CSV or XLSX files, or through OCR for scanned PDFs. Knowing the extractionMethod helps compliance staff interpret the extractionConfidence score — a high confidence score from a structured parse is more reliable than the same score from OCR. When issues appear in a batch, the extractionMethod is the first thing to check when deciding whether re-upload in a different format might resolve them.
