Insulin (Fasting Insulin)
Insulin is the hormone that helps move glucose out of the bloodstream and into your cells, where it can be used for energy. Think of it as the key that unlocks the cell door for fuel. When insulin levels are elevated, it can be an early warning sign of metabolic dysfunction, often years before blood sugar becomes abnormal.
Measuring fasting insulin is a powerful way to catch metabolic issues early and is just as important for long-term disease prevention as it is for optimizing energy, body composition, and performance.

Lab work FAQs
Please read our FAQs page to find out more.
How quickly will my lab results arrive?
Your lab results will typically arrive within two weeks, though processing time may vary based on the size and complexity of your panel. Rest assured, once your results are ready, they will be securely delivered to your email. No waiting rooms. No chasing paperwork. Just precision diagnostics at your fingertips.
Does Marek Diagnostics accept insurance?
Marek Diagnostics is a cash-pay service. Our platform offers direct access to comprehensive testing without the limitations, denials, or delays imposed by insurance companies. If traditional insurance covered the kind of proactive, high-quality lab work we offer, Marek Diagnostics wouldn’t need to exist.
However, many clients successfully use their HSA/FSA to cover their testing costs. Marek Diagnostics is partnered with TrueMed for convenient deployment of HSA/FSA funds at checkout.
My panel Meets Treatment Requirements — what does that mean?
Marek Diagnostics is an extension of Marek Health, the leading health optimization platform designed to turn your results into informed action.
If your panel Meets Treatment Requirements, you’re eligible to enroll into Guided Optimization, an exclusive program that connects you with:
- Detailed, expert led lab analysis
- A consultation with a Marek Health coach and board-certified medical provider
- A precision health optimization plan
- Access to high-quality treatment options
If you’re unsure what to do with your results, Marek Health is the bridge between lab results and achieving your goals.
Do I need to pay a separate fee at the lab to get my blood drawn?
No additional payment is required at the lab. Our expert-built panels include the venipuncture and if you’re building a custom panel or testing biomarkers individually, a $5 venipuncture fee will be automatically added at checkout.
