A 19 yr old lady attends the GP surgery for her booking appointment.  She thinks she is about 8 weeks pregnant. She feels a little nauseous and weary but has no significant past medical history and has not been taking any medication. Her full blood count is 

• Hb 80g/L
• MCV 71fL
• PLT 168×10*9/L
• WCC 8.9×10*9/L

What do you think of her FBC?

Are there any further blood tests you might request?

Do you have any further advice for her?
