The Schumm test (shoom) is a blood test that uses spectroscopy to determine significant levels of methemalbumin in the blood. A positive result could indicate intravascular hemolysis.{{Cite web|url=http://www.pathology.co.za/RCPA/schumms_.htm|title=SCHUMM'S TEST}}{{Cite web|url=https://www.healthtestingcenters.com/|title=Order Lab Tests, Blood Tests, or Home Test Kits Online | HTC|website=www.healthtestingcenters.com}} The Schumm test was named for Otto Schumm, a German chemist who lived in the early 20th century.{{cn|date=November 2021}}
