Comparative study on determination of alpha-hydroxybutyrate dehydrogenase, lactate dehydrogenase isoenzyme LDH-1 by adsorption on DEAE Sephadex A-50 & electrophoresis.

Serum alpha-hydroxybutyrate dehydrogenase (HBDH) and lactate dehydrogenase isoenzyme (LDH-1) levels by two techniques viz., adsorption on DEAE Sephadex A-50 and by electrophoresis were estimated in healthy subjects and patients with testicular tumours. The correlation coefficient between HBDH and LDH-1 by adsorption technique was found to be r = 0.8. HBDH was found to have a value almost twice that of LDH-1 by adsorption and electrophoretic technique and the activity of LDH-1 obtained by two methods and of HBDH in normals and patients with testicular tumours could be converted using a factor of 0.557. The quantitative method used for determination of HBDH is reliable, accurate, simple and rapid and therefore has better value in a clinical setting than electrophoresis and adsorption techniques which are laborious and time consuming.
