The AA. have tested 50 serum samples for immunoglobulins (IgG, IgA, IgM) with two different methods: laser-nephelometry (LN) and radial immunodiffusion (RID). Mean values of IgG and IgA are almost the same in the two tested methods and there is a good correlation between LN and RID (IgG: r = 0,98; IgA: = 0,96). Also IgM have showed a good correlation (r = 0,987) but mean values obtained with LN are just a few lower than those obtained with RID. Regression lines, calculated for all the Ig, confirm these conclusions. The AA. conclude affirming that the obtained difference for IgM is due to the different standards used for LN and RID determinations.
研究人员用两种不同方法（激光散射比浊法（LN）和单向免疫扩散法（RID））检测了50份血清样本中的免疫球蛋白（IgG、IgA、IgM）。两种检测方法中IgG和IgA的平均值几乎相同，且LN与RID之间具有良好的相关性（IgG：r = 0.98；IgA：r = 0.96）。IgM也显示出良好的相关性（r = 0.987），但LN法得到的平均值略低于RID法。为所有免疫球蛋白计算的回归线证实了这些结论。研究人员得出结论称，IgM所获得的差异是由于LN和RID测定所使用的标准不同。
