Carpal Tunnel Syndrome and Calcium Deposit in the Surgically Transacted Transverse Carpal Ligament

Table 4

The spike recoveries of Ca, Cd, and Pb of the ddH₂O. The determined concentrations were reported as the mean of three replicate experiments ± standard error of the mean (SEM).

Element	Concentrations (μM)
	Nominated concentration	Element concentration measured in a spiked ddH2O	Element concentration measured in an unspiked ddH2O	Recovery (%)	RSD (%)
Ca	50.0	47.3 ± 0.3	0.03 ± 0.0005	95 ± 0.02	0.63
Cd	50.0	49.6 ± 0.04	0.06 ± 0.0001	99 ± 0.01	0.080
Pb	50.0	46.7 ± 0.2	0.02 ± 0.0007	93 ± 0.03	0.40
