An online tool for the evaluation of pediatric blood counts accompanying our publication
Use the boxes on the left to enter patient test results. The two top-most boxes define the test date or the age at testing.
Patient data (i.e. sex and age) can be entered using the top-left tabs.
Navigate between test result entry (this page), graphical result display using percentile charts, and graphical result display using z-scores with the tabs at the top.
Add or remove measurements using the plus or minus symbols.
This Quick Guide disappears automatically once you add measurements.
Download percentile charts (including entered patient test results) as individual .pdf files:
Download all percentile charts (including entered patient test results) as a combined .pdf file:

This tool is a subproject of the PEDREF — Next-generation pediatric reference intervals initiative, a collaborative pediatric reference intervals initiative of the Department of Pediatrics, University Hospital Erlangen and our collaborators supported by the DGKL's Working Group on Guide Limits.
This web application visualizes the reference intervals from the abstract/upcoming publication above. While great care was taken in the programming of this web application and the creation of the reference intervals, there is no warranty for the program and/or reference intervals. In particular, this is not a medical device/product but an ongoing research project, and there is no responsibility for any medical decisions based on this web application.
https://www.pedref.org/hematology/z-score.php returns the z-score of a single analyte. Specify (as GET Query String parameters) patient sex (sex, male or female), patient age (age, in days, integer), analyte (analyte, see codes below), and value (value, floating point).
https://www.pedref.org/hematology/chart.php returns a percentile chart (.png) of a single analyte. Specify (as GET Query String parameters) patient sex (sex, male or female), patient age (age, in days, list of integers, ;-separated), analyte (analyte, see codes below), and value (value, list of floating point numbers, ;-separated). If mode=ZChart is specified (optional parameter), a z-chart is returned.
Analyte codes are Hb (Hemoglobin), Ht (Hematocrit), Thr (Platelets), Ery (Red cell count), Leu (White cell count), MCH, MCHC, MCV, RDW.
