 ===== Current Study Protocol =====
-Please note that the text below describes the procedures as they are employed during the ongoing [[3A|third]] assessment. The [[1A|baseline]]- and [[2A|second]] assessments differ in various ways, and Lifelines recommends consulting their respective wiki pages to learn more about the procedures employed at those times.

 ===== Sample Collection =====
-Adult participants were instructed to collect their urine over a full 24-hour period (08:00-08:00) as these samples are considered the "gold standard" to determine conditions such as albuminuria (Gansevoort RT et al. 2006(([[https://pubmed.ncbi.nlm.nih.gov/16936069/|Evaluation of measures of urinary albumin excretion]]))) and assessing kidney function.\\

 Underage participants (ages 8–17) were instructed to collect their urine over a 12-hour period (20:00-08:00) because of the inconvenience posed by the 3-liter containers.\\
 Participants were instructed to store their containers at room temperature during the sample collection procedure.

 ===== Sample Processing =====
-Urine samples are divided into 900 μl fractions by the [[https://synchronlab.com/product/xperimate-modular-robotic-pipetting-platform/|Synchron Xperimate robot]], a modular robotic pipetting platform. These aliquots can be identified by a unique 2D barcode printed on the bottom of the tubes, and are held within a 1D barcoded rack ([[https://www.lvl-technologies.com/en/sample-storage/safe-2d-tubes-engl/safe-96-it-2D|LVL technologies Safe® 96 IT]] or equivalent). The exact location of each individual sample is logged and continuously tracked in our LIMS.\\
