Re: Antiphospholipid testing and Systolic BP levels

We thank Dr Charkin for highlighting an ambiguity in the guideline in terms of levels of systolic blood pressure and apologize for this. Where diastolic bp is less than 90mmHg, we would recommend that a woman is referred on the same day if she has a systolic bp of 160mmHg or more, with or without proteinuria (and no other symptoms).

The PRECOG guideline is not primarily a hypertension guideline and has not therefore comprehensively addressed all permutations and combinations of new hypertension. We have rather focused on diastolic blood pressure, and on the implication of new hypertension in terms of the development of pre-eclampsia. The two references to systolic blood pressure levels were added on request, to highlight the potential risk from systolic blood pressure alone.
