Overview
Brief Summary
This is an observational prospective study. The main purpose is to evaluate the stability of the Bilistick system in a humid and hot climate compared to the quantitative test for serum bilirubin (SBR) measurement currently used, the BR-501 total bilirubin meter, kept in a controlled environment.
The secondary aim is to assess the operational feasibility of the Bilistick system in a tropical limited-resource setting, when used by locally trained nurses.
Detailed Description
Study procedure: 1. SBR will be measured in parallel with two tests during three distinct seasons. (Cold, hot, rainy). The Blood is from an extra capillary sample taken from a single heel prick done for routine SBR) BR-501 total bilirubin meter, the quantitative test for SBR currently used, will be kept in a controlled environment while the new bilirubin test (Bilistick system) will be exposed to tropical conditions. 2. Trained nurses will use the Bilistick system observed by a qualified laboratory technician; Usability of the Bilistick system by the trained nurses will be evaluated via a 5-point Likert scale questionnaire and focus groups discussions.

Eligibility Criteria
Inclusion Criteria
- •Written or thumb print for informed consent from the parent
- •Infant born ≥ 35 weeks of gestational age
- •Infant who needs a routine SBR measurement
- •Infant in stable clinical condition prior to SBR measurement confirmed by the trained nurses
Exclusion Criteria
- •The participant will not be enrolled in the study if ANY of the following applies:
- •Infant who already had 1 SBR measurement done with the Bilistick system
- •Last haematocrit measurement \> 65% or no previous haematocrit measurement
Outcomes
Primary Outcomes
Comparison of the agreement of serum bilirubin measurement between the two tests in three different seasons
Time Frame: 18 months
The main outcome of interest is the potential effect of environmental conditions on the quantitative outcome of the Bilistick System, using BR-501 bilirubin meter machine as a reference. The Bland-Altman analysis will be used to compare the two tests.
Within each season, evaluation of the impact of temporal variation on the agreement of serum bilirubin measurement between the two tests.
Time Frame: 18 months
A linear regression analysis will be done to look for statistically significant effect of exposure time on the difference between the average total bilirubin serum levels of the two tests.
Secondary Outcomes
- Evaluation of the usability of the Bilistick system using a 5-point likert scale questionnaire and a focus group discussions(18 months)
- Perception by the trained nurses of the Bilistick system usability with a focus group discussion (FGD).(18 months)
