Test could predict which mothers will need Caesareans

A test which could stop women labouring for hours in the hope of a "normal" birth only to end up with a Caesarean section has been developed in Sweden.

Researchers have established that when high levels of lactic acid are measured in the amniotic fluid, it is unlikely the mother will deliver vaginally.

Measuring this acid could help decide whether to end a difficult labour and opt for a Caesarean earlier.

The test is being rolled out in a number of European hospitals.
