Relevance of the jaundice meter in determining significant bilirubin levels in term neonates at a tertiary hospital in Lagos State

Correlation between Transcutaneous Bilirubinemia and Blood Bilirubinemia in Screening Term Newborn for Neonatal Jaundice at the Essos Hospital Centre (EHC), Yaoundé, Cameroon

“…We found a strong correlation between the two TcB testing sites (forehead and sternum) r = 0.91; our data are consistent with similar studies and protocols [8] [11] [12]. Conversely, for others, transcutaneous bilirubin measurements on the forehead had a better correlation with serum bilirubin [9] [13] [14]. The correlation between TcB/TsB in this study is consistent with other sites, which, although using other devices, have indicated a strong association between TcB and TsB measurements, with correlation coefficients ranging from 0.75 to 0.95 [9] [14] [15].The correlation coefficient as used in many literature works to investigate agreement between TsB and TcB may be unappropriated to decide which tools to use.…”

“…The sample of this study was mostly constituted of male infants at 55.6%. This profile is similar to those of Oyapero et al [9] and Madubuike [10] who had a high incidence of male infants in Nigeria.…”

In fact, correlation does not imply agreement, and that constitute a pitfall for many research works [16] [17].…”
