Hi , at my pre operation assessment I was told to have a blood test for sickle cell , which I’ have booked at my GP surgery for Monday 25th January . When my daughter was a baby she had her check ups and they found out my daughter is a sickle cell carrier . I also had bloods taken while I was pregnant and it came back negative to sickle cell – it was discovered that my daughters dad is a carrier of sickle cell . I assume Mya are just being careful and they want us to obtain GP letter to confirm whether we have sickle cell or not .
