According to Chemistry and Industry, the magazine of the Society of Chemical Industry, 1,000 women will be trialling this new test at St Richard's Hospital, Chichester, West Sussex.
The test monitors levels of urate, a salt of uric acid, in the saliva. Higher concentrations of urate are believed to be a marker for impaired kidney excretion in pre-eclampsia.
If the trials are successful, the spit test is expected to be more effective than current blood pressure and urine checks.
