Abstract
Abstract The invention relates to a process for the analysis of haemoglobin HbA 2 characterized in that it comprises the following steps a) mixing an anionic resin with a hemolysate of blood; b) agitation of the mixture obtained in (a), to obtain separation in two phases; c) filtration of the light phase containing haemoglobin HbA 2 ; and d) photometric analysis of the filtrate obtained in (c). The process permits the obtainment of a particularly rapid analysis of haemoglobin HbA 2 and allows the carrying out of batch analyses.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
A process for the analysis of haemoglobin A (HbA 2 ) characterized in that it comprises the following steps: a) mixing an anionic resin with a hemolysate of blood; b) agitation of the mixture obtained in (a) to obtain separation of said mixture into a heavy phase and an overlying light phase; c) filtration of said light phase; and d) photometric analysis of the filtrate obtained at step (c).
Claim 2
Dependent Claim
69 words
A process for the analysis of haemoglobin A (HbA 2 ) characterized in that it comprises the following steps: a) mixing an anionic resin with a hemolysate of blood; b) agitation of the mixture obtained in (a) to obtain separation of said mixture into a heavy phase and an overlying light phase; c) filtration of said light phase; and d) photometric analysis of the filtrate obtained at step (c).
