Your White blood cells are slightly high- This always needs to be interpreted in the proper context. While this may be the sign of an infection ( anything form a respiratory infection, to a UTI to sinusitis), this mildly elevated value can be seen from certain medications, from mild dehydration, or even as a "stress" response.
Your fasting glucose is a little high and can imply an "impaired glucose tolerance" , or an early form of diabetes/ or a predisposition to it- It should be repeated/ followed and possibly have a glucose challenge test.
The mild elevation of uric acid could be related to diet, or medications, or a genetic predisposition. Elevated uric acid can lead to gout.
The mild elevation of GGT is a liver enzyme- It should be interpreted in context with other liver tests, and by itself does not mean very much of concern. If other liver tests are elevated, further investigations are indicated.
Always ask if you need clarification/more information.
I doubt the sleep apnea is relevant to these labs.
Here is a good review on diet for hyperuricemia.
Uric acid levels result from purine metabolism. Elevated levels can be due to alcohol, certain medications and certain foods like meats, organ foods, and legumes.
I hope that helps.
