Updated Data
URXUCR was updated to correct the Limit of Detection, only six data points were affected.
- Albumin & Creatinine – Urine (ALB_CR_I 2015-2016)
2013-2014 Aldehyde – Serum datasets (ALD_H & ALDS_H) were updated to correct the Limits of Detection (LOD) for various analytes in the LOD table in both documentation files. However, only data for one analyte (LBXI5AL-Isopentanaldehyde)was updated, as the LOD was corrected from 0.119 ng/mL to 0.316 ng/mL.
- Aldehydes – Serum (ALD_H 2013-2014)
- Aldehydes – Serum – Special Sample (ALDS_H 2013-2014)
Documentation and SAS labels for the following pooled-sample datasets were updated to reflect the correct units the analyte values were reported in. No changes were made to the actual values of any analytes in these datasets.
