We described those that are particularly significant for elderly patients, namely: peripheral blood morphology, arterial blood gasometry, cancer markers. The aim of this article is to summarize current knowledge about laboratory tests important in geriatrics, as well as draw attention to the diverse use of laboratory tests in clinical practise. Keywords: laboratory tests; geriatrics; blood morphology
