Yes it is done in conjunction to gain risk level but figures can indicate other things. As all my other results were normal apart fomr the papp-a. Thanks for the reassurance but not stressing just wasnt gonna happen *L*

I now have a reaadjusted risk thanks tohaving my weight calculated into the equation.
It is now 1;232 and 1 : 6033 so a huge differene from 1: 16

Low Papp-a can still mean pre eclapmsia and IUGR so we shall just monitor more.
Thanks for your response I appreciate it.
