This protein fraction includes, among others: transport proteins (transporting hemoglobin – haptoglobin, copper – ceruplasmin, thyroxine -TBG and vitamin B12 – transcobalamin), α1— i a2— lipoproteiny, α1-seromukoid, α2-macroglobulina, α1-inhibitory protease.
When do we do?
1. Suspicion of a congenital deficiency of carrier proteins.
2. Suspicion of liver, kidney and gastrointestinal diseases.
Test material: serum.
Preparation for the test: on an empty stomach (at least 8 hours).
The course of the study: one-time blood sampling from a vein in the arm.
Time to wait for the result: 1 Day.
Standards:
α1– globulins – 2,1-3,5 g / l (3-5% of total protein),
α2– globulins – 4,9-7,0 g / l (7-10% of total protein).
Comments: Determination of α concentrations1-, a2-globulin is an element of serum protein electrophoresis.
