Fetal/maternal plasma lithium concentration ratios at E18. Closed symbols indicate acute treatment and open symbols indicate long-term treatment. Black symbols are samples measured using LA-ICP-MS and the blue symbols are ones measured using ICP-MS. Each point on the graphs represents a ratio calculated using fetal plasma levels in an individual fetus and the corresponding time-matched plasma of the dam.
