Product name and intended use~The VIDAS® NEPHROCLEAR™ CCL14 Test is intended to be used in conjunction with clinical evaluation in ICU patients with moderate to severe (stage 2 or 3) acute kidney injury (AKI) as an aid in the risk assessment for developing persistent severe AKI (stage 3 AKI lasting ≥ 72 hours) within 48 hours of patient assessment. The VIDAS® NEPHROCLEAR™ CCL14 Test is intended to be used in patients 21 years of age or older.~Product description~The VIDAS® NEPHROCLEAR™ CCL14 Test is an automated assay for use on the VIDAS® 3 instrument for the immunoenzymatic quantitative determination of C-C motif chemokine ligand 14 (CCL14) protein in human urine using the Enzyme Linked Fluorescent Assay (ELFA) technique.~Trial Design Overview~This VIDAS® NEPHROCLEAR™CCL14 (VIDAS® NCL™ CCL14) clinical trial is a multicenter, prospective, and qualitative study. 40 to 80 samples collected and tested from subjects enrolled in a related trial will also be tested on the VIDAS® 3 instrument and test.~Trial objectives~The objective of this trial is to identify suitable storage conditions for samples tested using the VIDAS® NCL™ CCL14 for the full measuring range of the assay (0.2 ng/mL to 30 ng/mL). To this end, samples will be tested under the following conditions:~Fresh, and tested within approximately 2 hours of collection,~After one freeze-thaw cycle,~After two freeze-thaw cycles,~After storage at ambient temperature for approximately 5 hours (tested 5 to 7 hours from collection time), and~After storage at 2 - 8 ºC for approximately 24 hours (tested 24 to 26 hours from collection time)~Samples collected from at least 40 subjects with urine CCL14 levels spanning the assay measuring range will be analyzed among these conditions.
This VIDAS® NEPHROCLEAR™ CCL14 (VIDAS® NCL™ CCL14) Sample Stability clinical trial is a multicenter, prospective, and qualitative study. The main study objective is to determine sample stability conditions for the VIDAS® NEPHROCLEAR™ CCL14 Test. This test is intended to be used in conjunction with clinical evaluation in ICU patients with moderate to severe (stage 2 or 3) acute kidney injury (AKI) as an aid in the risk assessment for developing persistent severe AKI (stage 3 AKI lasting ≥ 72 hours) within 48 hours of patient assessment. The VIDAS® NEPHROCLEAR™ CCL14 Test is intended to be used in patients 21 years of age or older.
