What type of blood tests should be ordered when checking brain fog?

Sex hormones (testosterone, e2, shbg)
Vitamin d

What else?

Before the CPAP I’d wake up tired. Now with the CPAP I’d wake up ok most mornings. I wear it between 3-5 hours. Sometimes 2 hours before I’d rip it off. But I still feel better. Are the initial hours helping me enough that it reduces sleep apnea the next hours?
