Abbott Laboratories on Tuesday posted stronger revenue and sales in the first quarter as contributions from its Covid-19-testing services drove higher diagnostics revenue.

The Abbott Park, Ill.-based healthcare-products company logged diluted earnings of $1 a share, up from 31 cents a share in the same three-month period a year earlier. The company's net earnings grew to $1.79 billion, from $564 million in the year-ago period.

Revenue grew by 35%, to $10.46 billion, from $7.73 billion a year earlier. Analysts were expecting revenue of $10.69 billion

Driven by the company's role in providing Covid-19 testing, Abbott's diagnostics revenue more than doubled, to $4.01 billion.

Nutrition sales grew 6.9%, to $2.04 billion. Sales of established pharmaceuticals improved by 2.5%, to $1.07 billion. Medical-devices revenue grew by 13%, to $3.32 billion.
