ABL90 FLEX PLUS Clinical Precision Study for ctBil and FHbF Parameters in Neonatal Whole Blood
Study Details
Study Description
Brief Summary
Conducting the ABL90 FLEX PLUS Clinical Precision Study for ctBil and FHbF Parameters in Neonatal Whole Blood is to validate performance claims for precision of the ABL90 FLEX PLUS ctBil and FHbF parameters in neonatal whole blood while being influenced by testing environment that is representative of intended use environment, site variability, intended use testing environment and operator variability in a Point-of-Care (POC) setting.
The investigational device is the ABL90 FLEX PLUS incl. consumables, running SW3.5 MR2, manufactured by Radiometer Medical ApS.
The study is being conducted in Denmark and in total, a minimum of 54 subjects are to be enrolled to provide successful measurement values from 3 different sites.

Detailed Description
The conduct of the clinical study is to determine the repeatability of ctBil and FHbF parameters in neonatal whole blood using contrived fetal cord blood from umbilical cord/placenta measured by the intended users in syringe, short probe, and capillary modes available for ABL90 FLEX PLUS, in a POC setting.
The primary endpoint is the Repeatability (SD) for each parameter, parameter level and measuring mode, pooled across sites.
Participating sites are maternity wards or similar site conducting planned cesarean sections. Pregnant women 18 years of age or older admitted to the maternity ward to undergo cesarian section after week 38 of gestation will be enrolled in the clinical study. When the subject has signed ICF, the site will collect cord blood from umbilical cord/placenta and when relevant prepare contrived samples by having access to adult type 0 Rh neg whole blood for diluting HbF in cord blood.
Three POC users, such as a nurse, a physician, or a therapist that care for the woman in the maternity ward will perform all measurements and they shall contribute evenly to the total number of samples measured. Replicate measurements shall be performed by the same user.
6-10 mL of cord blood is collected in a blood collection syringe from each umbilical cord/placenta, contrived, and the sample is aliquoted into 5 safePICO aspirators (max volume 1.5 mL) or into 25 capillary tubes.
At each site, samples will be collected for the 2 parameters, 3 modes and 3 levels, completing measurements from minimum of 18 samples from 18 subjects.
