I guess you mean HBDH.
Alpha-hydroxybutyrate dehydrogenase (HBDH) is an enzyme in the myocardial enzyme spectrum that is ubiquitous in mammals. Its activity is comparable to an isozyme of lactate dehydrogenase. Can reflect myocardial damage, common muscle damage, red blood cell damage.
If other items,such as LDH 、CK/CK-MB is OK, no need to worry.
