IVF smoking test

Hi All,

Me and my partner are about to start <a href="https://glowing.com/glow-fertility-program">IVF</a> through NHS. My partner quit “smoking” about 8 months ago and just vapes now.

Does anyone know if this shows up in carbon monoxide test for smoking or most importantly if it will affect things??

S many conflicting information online was hoping someone can advise that’s been through this :/ xx
