Table 3

Comparison of serum calcium, phosphorus, alkaline phosphatase, creatinine and electrolyte levels at 28–30 weeks and 30–32 weeks of gestational age in preterm babies.

S. No.	Parameters	Cases (𝑛=25)	Cases (𝑛=25)	𝑃-Value
		28–30 weeks	30–32 weeks
(1)	Serum Calcium (mg/dL)	7.044±1.753	8.176±1.771	NS
(2)	Serum Phosphorus (mg/dL)	3.012±0.799	4.256±1.126	NS
(3)	Serum Alkaline Phosphatase (IU/L)	625.56±176.28	503.48±164.37	NS
(4)	Serum Creatinine (mmol/L)	67.64±7.4	58.52±3.8	NS
(5)	Serum Sodium (mmol/L)	136.6±4.1	134.04±2.71	NS
(6)	Serum Potassium (mmol/L)	6.98±0.72	6.16±0.48	<0.01

It is evident from this table that serum calcium & phosphorus levels are decreased (statistically insignificant) whereas alkaline phosphatase, creatinine and electrolytes level are insignificantly increased at 28–30 weeks as compared to 30–32 weeks of gestational age in preterm babies.
