I am a 44 yr. Old female with long history of hypoglycemia & hypothyroid. Recaently have had other symptoms too. Dr. Ordered, in addition to tsh test some tests i'm not familiar with. A panel of tests labeled "basic metabolic(bun,calcium, chloride, co2,creatinine,glucose,potassium,sodium) and a test called hgb a1c. Does anyone know what these tests are used to check for? Any info appreciated.
In addition to low thyroid symptoms, i'm having problems with low blood pressure, muscle spasms, and tingling and numbness in my hands and feet. Thanks for any replies.
