Blood Sugar
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Blood should be drawn in the morning after an overnight fast. Per the American Diabetes Association (ADA), fasting is defined as no caloric intake for at least eight hours.
Glucose is the primary energy source for cellular metabolism and is tightly regulated by hormonal mechanisms involving insulin, glucagon, cortisol, and other metabolic pathways. Measurement of blood glucose is fundamental in the diagnosis and monitoring of metabolic disorders such as diabetes mellitus, hypoglycemia, and insulin resistance. Fasting plasma glucose, random glucose, and oral glucose tolerance tests (OGTT) are standard approaches used to assess glycemic status. Persistent hyperglycemia is diagnostic of diabetes, while low levels may be seen in insulinoma, adrenal insufficiency, or reactive hypoglycemia.

Statement on Medical Necessity
All ordered tests should be medically necessary for the diagnosis or detection of disease, illness, impairment, symptom, syndrome, or disorder and the results should be used in the medical management and treatment decisions for the patient. Solaris requires ICD-10 codes with each order for lab testing and both the tests ordered and the diagnosis should be documented in the provider’s medical record for the patient. The United States Department of Health and Human Services, Office of Inspector General, takes the position that a provider who orders medically unnecessary tests may be subject to civil penalties.
Panels and Profiles
Solaris offers Providers the convenience of ordering test combinations in a group at times with the flexibility to choose appropriate test(s) for individual patients. Providers should only order those tests that he or she believes are medically necessary for each patient, and a lesser inclusive profile or individual tests should be ordered if not all tests in the test combination/profile are medically necessary. All tests offered in a test combination/profile may be ordered separately as individual tests. Solaris encourages clients to contact their Solaris representative if the testing configurations shown do not meet individual needs for any reason, or if some other combination of procedures is needed.
