Hello doctor,

I am in the eighth week of an IVF pregnancy. I have already had three miscarriages before. I am on Filgrastim injections (10 units of insulin syringe), Dexona, Duphaston, Estrabet 2 mg two tablets thrice a day. My doctor got some blood tests done yesterday. The TLC was at 21000 per microliter of blood. So, the doctor told me to get this repeated today. Today my TLC count was 21000 per microliter of blood. Could you please tell me if this increased level is fatal for my baby? Should I be worried?



Welcome to

The Filgrastim injection that you are taking is responsible for the elevated TLC (total lymphocyte count). But you need not worry as the function of the Filgrastim is to cause multiplication of the white blood cells. Studies have shown that Filgrastim after IVF (in vitro fertilization) improves the implantation rate of the embryo. So, in your case, it is helping your pregnancy and preventing miscarriage. It is not going to harm your baby. So, you can relax and follow your doctor's instructions.
