UK researchers have pioneered a venopuncture-free test for drug dosages in premature babies.
The study, which involves the use of blood spots obtained from a simple heel-prick, took place in the Belfast Hospital for Sick Children and involved 32 neonates.
The study involved the antibiotic metronidazole.
Researchers used single drops of blood collected on blotting paper from premature infants who were receiving the drug as part of their routine care.
The “spots” were dried and the results used to develop dosage guidance for doctors.
