Does hyperventilation cause lower CO2 results in a blood test?

Persistent735395
I took lab tests for my accutane prescription and my Co2 came back 1 point less than the reference bracket. 19 L. I have a major fear of needles and blood so during my blood draw, I was breathing heavy with anxiety and almost passed out. I wonder if this could take an effect on my CO2 levels or if I need to have a cause of concern for a more serious condition. It might be important to add that I am not prediabetic nor diabetic.
