Annals of Laboratory Medicine deposits all published content in Similarity Check, a multi-publisher initiative started by CrossRef to help scientific publishers actively engage in efforts to prevent scholarly and professional plagiarism. Similarity Check is distinct from other plagiarism screening tools with its continuously growing database of current and archival scholarly literature. Wherever you see the "Similarity Check" logo, you can be reassured that the publisher whose content you are reading deposits into Similarity Check and is committed to publishing original research.
