As a practicing printmaker Stephen has recently completed four giant Kites commissioned by the banking group Lloyds TSB.

Usually all newborns (neonates) delivered in the hospital will have total serum bilirubin (TSB) measured in the clinical laboratory on one or more blood samples as requested by attending pediatricians.
To obtain a blood sample for TSB, a phlebotomist takes blood from the infant's tissue (usually the heel) rather than from a vein, as the veins of newborns are extremely small and easily damaged.
In the TSB test, spectrophotometry is used to identify and quantify the amount of bilirubin in a specific amount of serum by measuring the amount of ultraviolet light absorbed by bilirubin pigment in the sample.
