Editing Pyruvate kinase deficiency (section)

==Diagnosis==
The diagnosis of pyruvate kinase deficiency can be done by full [[Complete blood count|blood counts]] (differential blood counts) and [[reticulocyte]] counts.<ref name=":1">{{Cite book|url=https://books.google.com/books?id=99YPDvFWBB0C|title=NORD Guide to Rare Disorders|last=Disorders|first=National Organization for Rare|date=2003-01-01|publisher=Lippincott Williams & Wilkins|isbn=9780781730631|page=496|language=en}}</ref> Other methods include direct enzyme assays, which can determine pyruvate kinase levels in erythrocytes separated by density centrifugation, as well as direct DNA sequencing. For the most part when dealing with pyruvate kinase deficiency, these two diagnostic techniques are complementary to each other as they both contain their own flaws. Direct enzyme assays can diagnose the disorder and molecular testing confirms the diagnosis or vice versa.<ref name=":0" /> Furthermore, tests to determine [[bile salts]] (bilirubin) can be used to see whether the [[gall bladder]] has been compromised.<ref name=":1" />
