测定血液和其它生物试样中乳酸的含量具有临床和研究价值。以前采用的 Summerson-Barker 法,LDH 酶终点法皆因精度不高、速度不快及费用太贵等原因不利于推广。酶电极研究工作的开展,诞生了新一代快速、精确、价廉的检测工具——LDH 电极。Willi-ams 等报道了 LDH 电极的研究工作,其电极反应原理为 Determination of blood and other biological samples of lactic acid content has clinical and research value. Previous Summerson-Barker method, LDH enzyme end point method due to the accuracy is not high, unpleasant speed and the cost is too expensive and other reasons not conducive to the promotion. Enzyme electrode research work, the birth of a new generation of fast, accurate, inexpensive detection tool - LDH electrode. Willi-ams et al reported LDH electrode research work, the electrode reaction principle is
