See what's happening beneath "normal." Functional Lab Testing in McKinney

A 100+ biomarker panel, explained in plain language and retested so progress is measured.

Dr. Cas reviewing results on a tablet with a patient

Functional lab testing in McKinney is where your plan begins. Most people have had “normal” bloodwork that didn’t match how they felt. Standard labs are built around insurance codes, so early warning signs often go unmeasured until something breaks. A functional panel looks wider and reads closer.

What the panel looks at

  • Vitamin and mineral status
  • Heart health and inflammation
  • Metabolism, blood sugar and diabetes risk
  • Thyroid and adrenal function
  • Sex hormones and prostate health
  • Liver health, immune strength and possible infections

Toxins, genetics and gut health are measured with add-on testing.

How Dr. Cas reads your results

He reviews every result, then sits down with you to explain what each number means. Together you build a plan around your goals, and you retest on schedule so the plan gets refined with real data.

Transparent, cash-pay labs

Specialty testing runs through Vibrant America, so it isn’t limited by diagnosis codes and costs stay transparent. Routine draws are done in the clinic for a $15 draw fee. Each full panel is valued at $375 à la carte and included two to four times a year in every membership. Compare memberships →

Questions

Why don't you bill insurance for labs?

Insurance generally pays for a test only when a diagnosis code justifies it. Vibrant America is cash-pay, so Dr. Cas can order what your situation calls for, and you see the price up front.

How long do results take?

Routine labs often come back within 10 to 14 days. A full specialty baseline takes about four weeks.

How are samples collected?

Depending on the test, from blood, urine, stool, saliva or a swab, in the clinic or at home. You'll get clear instructions either way.
