METHODS: We reported two cases of false elevation of MCHC. Considering the possibility of cold agglutination and lipid blood interference detection, we used 37℃ water bath and plasma exchange to correct for interference on the sample.
RESULTS: After correcting the interference, MCHC returned to normal, consistent with the patient\'s disease status. Therefore, the two cases of abnormal elevation of MCHC are considered to be pseudo elevation caused by interference.
CONCLUSIONS: For specimens with abnormally elevated MCHC levels, experimenters should first analyze possible interfering factors and choose effective methods to correct different interferences, providing accurate testing reports for doctors and patients.
方法:我们报告了2例MCHC假性升高。考虑到冷凝集和血脂干扰检测的可能性,我们使用37℃水浴和血浆置换来校正对样品的干扰。
结果:校正干扰后,MCHC恢复正常,与患者的疾病状态一致。因此,2例MCHC异常抬高均为干扰引起的伪抬高。
结论:对于MCHC水平异常升高的标本,实验者应首先分析可能的干扰因素,并选择有效的方法来纠正不同的干扰,为医生和患者提供准确的检测报告。
