Is a simple coagulation lab test (pt/ptt inr & fibrinogen) sufficient to diagnose protein c, protein s or factor v leidmen mutation disorders?

No: There are specific tests for each of the disorders you listed.

Not by itself,,,: This is an essential test that helps a lot to determine whether or not a person has these diseases, and should be included in the workup of all of them but other specific tests, like aPTT, Protein C and Protein S antigen are needed to distinguish any of these. Also genetic testing may be important in all diseases. Best of luck.

No there isn't.: Each test for protein C , protein S deficiency, and FVL mutation is separate.
