Determination of the Catalytic Activity
Concentration in Serum of
L-
Alanine
Aminotransferase (EC 2.6.1.2, ALAT)
BASED ON THE IFCC ALAT REFERENCE METHOD (2)
This ECCLS standard is based on the corresponding IFCC Refe–
rence Method for determination of ALAT, which has been adap–
ted by this ECCLS Subcornmittee for routine
~se
in European
clinical laboratories, as described for CK in the General
Introduction to the ECCLS standard Method l.
This standard recornrnends reaction conditions and describes
the tolerance lirnits for variations in rneasurernent procedures
that nevertheless allow routine determinations of the cataly–
tic activity concentration of ALAT to be equivalent to those
of the unrnodified IFCC ALAT Reference Method.
For details not given in this standard refer to the original
IFCC docurnent, ALAT, part 7 of the IFCC rnethods for rneasure–
rnent of catalytic concentration of enzymes (14).
The reference nurnbers refer to the reference list for the
ASAT rnethod.
