Hello and welcome to e health forum.
The history provided is very minimal. For proper assessment of your lab findings, it is important to know what symptoms you have in the first place.
In most cases the findings you have mentioned, can be very benign.
Monocyte count can be elevated, due to common cold infections or allergic situations.
The low creatine levels are insignificant, and could be a age specific finding.
In case the rest of the serum electrolytes and blood tests are within normal, the PCO2 levels could be a sign of hyperventilation, associated with anxiety.
You may consult with your doctor, who can examine you and provide you proper help.
