Electrochemiluminescence Immunoassay (ECLIA) in 92 children (67 boys, 25 girls) aged 3
months to 12 years at admission to hospital (timepoint 1, T1) and at discharge (timepoint 2,
T2). There was a significant fall in the mean 25 (OH) D from T1 (71.87±27.25 nmol/L) to T2
(49.03±22.25 nmol/L)(mean change= 22.84 nmol/L, P value= 0.0004). Proportion of patients
having VDD (levels< 50 nmol/L) at admission (25%, 23/92) increased significantly at the …
