<br /> SEOUOIA ANALYTICAL Please Note:
<br /> y The LGS Is a control sample of known,interferent free matrix that is analyzed using the same reagents,
<br /> preparation and analytical methods employed for the samples. The LCS%recovery data is used for
<br /> validation of sample batch results. Due to matrix effects,the QC limits for MS/MSD's are advisory only
<br /> Edana M. Fruciano and are not used to accept or reject batch results.,
