DIFFERENTIAL DIAGNOSTIC TECHNIQUE FOR CHRONIC GLOMERULONEPHRITIS FORMS WITH CHRONIC RENAL INSUFFICIENCY AND WITHOUT RENAL INSUFFICIENCY Russian patent published in 2009 - IPC A61B5/00 G01N33/53 

FIELD: medicine; nephrology.

SUBSTANCE: evaluation of IgA, IgM, IgG levels is combined with calculation of y₁ and y₂ values by linear discriminator (LD) equation of general formula: where C is a constant, x_i represents informative signs, namely x₁ is IgA level, x₂ is IgM level, x₃ is IgG level, a_i represents factors for specified signs. Two y values are calculated with factors a related to each y value; and C constant by formulas: y₁=-6.958+0.298x₁+1.935x₂+0.272x₃; y₂=-5.668+0.688x₁+1.559x₂+0.175x₃. Provided y₂ exceeds y₁, a patient is referred to the group without chronic renal insufficiency. In case y₁ exceeds y₂, a patient is considered to be related to the group of patients suffering from chronic renal insufficiency.

EFFECT: improved performance of diagnostics that further ensures effective realisation of set of actions aiming at prevention of the given pathology.
