Transcutaneous bilirubin (TcB) measurement is a non‐invasive method for measuring serum bilirubin level (Dai 1997). Transcutaneous bilirubinometry works by directing light into the skin and measuring the intensity of the wavelength of light that is returned (Boo 2007).

2014年6月1日 · The American Academy of Pediatrics recommends universal screening with TSB or transcutaneous bilirubin (TcB) levels, or targeted screening based on risk factors. 5 Universal TSB/TcB screening...

2010年8月15日 · Results were plotted against hour-specific bilirubin nomograms proposed by the American Academy of Pediatrics (AAP), and total serum bilirubin (TSB) testing was performed immediately if the TcB...

TcB is an inexpensive, noninvasive and precise pre-discharge screening test for evaluation of hyperbilirubinemia, with a high PPV. It is highly recommended to be performed routinely due to high incidence of hyperbilirubinemia in neonates.

2024年12月6日 · Transcutaneous bilirubin (TcB) is a non-invasive procedure used to detect hyperbilirubinemia in newborns. It is a safe alternative to total serum bilirubin (TSB) measurement, which is the gold standard for diagnosing hyperbilirubinemia but …

2023年11月22日 · Transcutaneous bilirubinometry (TcB) is an increasingly applied noninvasive, painless, easily reproducible, and cost-effective point-of-care alternative to estimate TSB. 3–5 TcB measures cutaneous bilirubin by directing light into the skin and measuring the intensity of reflecting specific wavelengths. 6

2023年8月16日 · TcB is an accurate estimation of serum bilirubin when test-negative: ruling out clinically significant hyperbilirubinemia. Test-positive tests require a serum bilirubin. The TcB meter has been a well-known point-of-care device for more than two decades.

2015年2月1日 · They nevertheless conclude that TcB measurements “provide reasonably accurate estimates of TSB values” and work well enough as a method for identifying significant hyperbilirubinemia. Because many nurseries now follow the recommendation to screen all infants with a TSB or TcB before discharge, 2 it is important to know whether we can rely ...

• TCB screening is recommended after the first 24 hours of life in all visibly jaundiced babies of 35 weeks gestation or greater. • Babies who are less than 24 hours old must have a blood test performed within 2 hours of jaundice being identified. • TCB should be performed within 6 hours where jaundice is suspected in

2023年5月9日 · The sensitivity of various TcB cutoff values to detect significant hyperbilirubinaemia ranged from 74% to 100%, and specificity ranged from 18% to 89%. Authors' conclusions: The high sensitivity of TcB to detect hyperbilirubinaemia suggests that TcB devices are reliable screening tests for ruling out hyperbilirubinaemia in newborn infants.
