Right now, I am working at a facility that does not own a TC bilimeter

At my previous job, we did a TC bili at 36h with the PKU, that way, if it plotted out to above the 75th percentile on the Bhuttani graph, we could do a serum at that time. What I love about having a TC bilimeter on the unit is that you can spot check any baby, anytime. Every hospital i have ever worked in does T and D bili, H&H and retic on coombs + babies at 24 hours of age or earlier for perceived jaundice.
