A mean tear/serum lithium ratio of 0.77 +/- 0.06 was found in 13 volunteers who were given lithium carbonate for 7 days. This finding differs considerably from those of another study, which reported tear and plasma lithium levels to be quite similar. It is suggested that measurement of tear lithium concentration has no clinical utility and that further research along these lines should be discouraged.
在13名服用碳酸锂7天的志愿者中，发现平均泪液/血清锂比值为0.77±0.06。这一发现与另一项研究的结果有很大差异，后者报告泪液和血浆中的锂水平非常相似。有人认为，测量泪液中的锂浓度没有临床实用价值，不鼓励沿着这些方向进行进一步研究。
