<strong>LDL</strong>-C <strong>Plus</strong><br />
C. Uma comparação num analisador Roche/Hitachi 911 da determinação<br />
do colesterol-<strong>LDL</strong>, utilizando o ensaio colesterol-<strong>LDL</strong> plus da Roche<br />
(y) com a determinação do colesterol-<strong>LDL</strong> PVS (x), teve como resultado<br />
as seguintes correlações (mg/dl):<br />
Passing Bablok 15,16 Regressão linear<br />
y = 1,77 +0,97 x y = 5,86 + 0,94 x<br />
r = 0,983 r = 0,983<br />
SD (md 95) = 8,56 Sy.x = 4,50<br />
Número de amostras medidas: 49<br />
As concentrações das amostras variaram entre 58,6 e 216,3 mg/<br />
