Study summary

Newborn jaundice, or accumulation of bilirubin molecules in blood, affects 60-80% of newborns and, in severe cases, places newborns at risk of brain damage and death. Universal screening of all newborn for jaundice ensures that at-risk newborns are identified and treated early. The bili-ruler is a low-cost ($10) plastic icterometer which could enable accurate and timely identification of jaundice in diverse settings.

The objective of this study is to evaluate the ability of bili-ruler to identify jaundiced newborns in their first week of life, compared to traditional methods of jaundice screening: visual inspection and transcutaneous bilirubinometry.

Read the detailed description

Neonatal jaundice, or accumulation of bilirubin molecules in blood, places newborns at risk of brain damage and death. Hyperbilirubinemia, or severe bilirubin levels above approximately 15 mg/dL, is a secondary outcome in the PRISMA MNH study. Newborn jaundice accounted for 13.09 deaths per 100,000 in 2016, and the burden is highest in South Asia and sub-Saharan Africa, where neonatal jaundice is the 7th and 8th leading cause of newborn mortality, respectively. Universal screening is recommended, but the standard of care, visual inspection of the skin and sclera, has a low sensitivity of 42%. Transcutaneous bilirubinometers are promising noninvasive, handheld tools, but they are expensive (> $3000) and inaccurate in newborns with darker skin. In low-and-middle-income countries, as well as in rural settings, guardians and clinicians often fail to identify at-risk newborns due to a lack of appropriate, affordable, and accurate screening tools. The bili-ruler is a $10 ruler with six shades of yellow, which could enable jaundice screening with high sensitivity in diverse settings such as homes, mobile clinics, and rural areas.

In this study, we will evaluate jaundice in newborns using three noninvasive techniques: bili-ruler, visual inspection, and transcutaneous bilirubinometry (a handheld device). The goals are to determine whether the six bili-ruler shades of yellow can be accurately correlated with bilirubin levels measured by a transcutaneous device, as well as to evaluate whether many users from various backgrounds can easily use bili-ruler to obtain comparable measurements. Additionally, limited evidence exists on the progression of jaundice and the performance of noninvasive screening tools in premature newborns and in newborns with various skin tones, especially darker skin tones. We seek to address this gap by utilizing an existing multi-site, international collaboration (the Pregnancy Risk, Infant Surveillance, and Measurement Alliance, or PRISMA) and enrolling large, diverse study populations. This study is nested in the PRISMA Maternal and Newborn Health (MNH) study, which is an open-cohort study that assesses pregnancy risk factors and associated maternal and infant outcomes in six study sites in five countries. All six study sites, located in Ghana, Zambia, Kenya, Pakistan, and India, will participate and collect bilirubin and jaundice-related data at four time points (0-3, 3-5, 5-7, and 7-14 days of life). The investigators will evaluate agreement between the three methods and agreement between bili-ruler measurements taken by two independent users. The investigators will additionally evaluate the impact of gestational age and skin tone on the accuracy of bili-ruler. Finally, the investigators will assess factors that influence bilirubin measurements.

Study population

All infants who are born to mothers in the catchment areas covered by PRISMA study sites

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • All infants who are born to PRISMA enrolled mothers will be eligible for this study.

Exclusion criteria

Exclusion Criteria:

  • Presence of skin lesions, abnormalities, etc on the baby's nose, face, and ears, which could interfere with measurement, as determined by research staff.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

What researchers measure

Primary outcomes

  1. Bilirubin

    Bilirubin levels will be assessed using Bili-ruler and a transcutaneous bilirubinometer (the Mennin Medical BiliCare device) at 0-3 days of life.

    Time frame: 0-3 days of life

  2. Bilirubin

    Bilirubin levels will be assessed using Bili-ruler and a transcutaneous bilirubinometer (the Mennin Medical BiliCare device) at 3-5 days of life.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 28, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
