## What is BiliCalc?

Designed by a pediatrician, BiliCalc uses the American Academy of Pediatrics 2004 "Management of Hyperbilirubinemia in Infants Greater than 35 Weeks of Age" to calculate the threshold for starting phototherapy based on the patient's age, bilirubin level, and neurotoxicity risk. Values are now displayed on the phototherapy nomogram. In addition, it will also tell you the patient's risk zone using the Bhutani Nomogram.

Allows direct age input and includes the option to calculate age from birth and lab sample times. The app has a direct link to source journal articles, nomograms, and a list of the neurotoxicity risk factors. Supports US and SI units (mg/dL and µmol/L).

App Feature Summary
-Calculates phototherapy threshold for newborns 35 weeks and older
-Displays values on phototherapy nomogram
-Suggests time frame for followup bilirubin levels based on patient risk zone 
-Direct links to reference journal articles

**********************************
Frequently Asked Questions
**********************************
1. I think the graph is backwards. Why is low risk on top and high risk on bottom?

The graph is directly from the 2004 AAP Hyperbilirubinemia Guidelines. The degree of "risk" refers to the infant's risk for developing neurotoxicity. This is different than the Bhutani Nomogram in which "risk" refers to the risk for development of severe hyperbilirubinemia. The threshold for treatment (when a data point lies above one of the lines on the graph) of the infant is different based on the predisposing factors (divided into the three risk categories). Babies who are "low neurotoxicity risk," can tolerate higher levels of bilirubin than a baby with medium or high risk. Therefore, a high risk baby will be treated at lower bilirubin levels than a low risk baby. The graph is correct in having low risk on top since a higher value is needed to pass the threshold for treatment (phototherapy). Please see the graph here for verification as well: http://bit.ly/AppPWU. Please email if you have further questions.

Intended for use by pediatricians, neonatologists, physicians, medical students, and pediatric nurses who treat newborn infants in the hospital and as outpatients.

### 1/5 — Outdated

*2026-08-04, version 2.8*

This app is now outdated. This was written to the 2004 guidelines and bili standards were updated in 2022. There are other tools that are based off of 2022 guidelines. Don’t buy this one!

### 3/5 — Not up to date guidelines

*2024-10-25, version 2.8*

It’s a great app and easy to use but needs to be updated to the 2022 guidelines.

### 1/5 — Used to be a 5star app

*2024-08-28, version 2.8*

The app still uses the old 2004 AAP guidelines and has not been updated to the 2022 guidelines. It appears to be effectively abandoned by the owner.
