Have I been over-tested by doctors?

On August 9, 2024, around 4 a.m., I sought medical attention due to suspected food poisoning from takeout, with symptoms of headache and nausea. The attending physician diagnosed me and ordered 28 tests. However, I disagree with 19 of these tests, believing they are unreasonable and excessive. The 19 tests in question are as follows: serum creatine kinase test, serum creatine kinase MB test, serum lactate dehydrogenase test, serum α-hydroxybutyrate dehydrogenase test, glycylproline dipeptide test, serum amyloid protein test, glucose test, serum alkaline phosphatase test, serum cholinesterase test, serum total protein test, serum albumin test, serum uric acid test, serum total bilirubin test, serum direct bilirubin test, serum indirect bilirubin test, serum total bile acid test, serum aspartate aminotransferase test, serum alanine aminotransferase test, serum potassium, sodium, chloride, and calcium tests. I believe these tests exceed the necessary scope of diagnosis and may constitute over-medicalization, resulting in an unnecessary financial burden. Please have relevant peers review whether this constitutes over-medicalization.
