Embryo ratings ABC IVF

[INFOHUNGRY]

Hi,

We're on day 3 post egg collection at ABC IVF and we had a call to report 8 embryos with grades 1 to 4. We think they said Grade 1 was the best but looking online it's really confusing. Does anyone know if clinics use their own grading systems and if so which one ABC use?

Hiya we used ABC. All embryos are grader the same way - grade 1 is the best and 4 is the lowest.
