Final answer:
Fasting specimens for bilirubin analysis are preferred because eating can affect the results.
Step-by-step explanation:
The statement 'Fasting specimens for bilirubin analysis are preferred' is True. When testing for bilirubin levels, fasting specimens are preferred because eating can affect the results. Bilirubin is a pigment that is produced when red blood cells break down, and fasting helps to avoid interference from food that could alter the bilirubin levels in the blood.
