Functional Medicine & Biological Age Testing

Bliss MD offers comprehensive functional medicine diagnostic panels through Vibrant Wellness and Mosaic Diagnostics, covering hormones, gut microbiome, inflammation markers, and genetics. The clinic also provides TruDiagnostic DunedinPACE DNA methylation testing to measure biological age — going well beyond standard bloodwork to give a full picture of cellular health and longevity risk factors.

Bliss MD Chicago brings clinical-grade functional medicine diagnostics to Lincoln Park, using next-generation laboratory partners that most conventional practices do not offer. Their testing menu is built around identifying the underlying drivers of dysfunction rather than managing symptoms after they appear. At the core is functional medicine panel testing through Vibrant Wellness and Mosaic Diagnostics — two of the most comprehensive specialty labs available in the United States. These panels cover an expansive range of biomarkers including advanced hormone profiles (cortisol rhythm, sex hormones, DHEA, thyroid axis), gut microbiome diversity and pathogen screening, systemic inflammation markers (hs-CRP, homocysteine, oxidative stress), micronutrient deficiencies, and genetic polymorphisms that affect metabolism and detoxification. Alongside these multi-system panels, Bliss MD offers TruDiagnostic DunedinPACE epigenetic biological age testing — a clinically validated DNA methylation assay that measures how fast you are aging at the cellular level. Unlike chronological age, biological age reflects the cumulative impact of lifestyle, stress, and environment on your genome. DunedinPACE is among the most accurate pace-of-aging clocks available, used in academic longevity research worldwide. Results are interpreted during a dedicated consultation with Dr. Thakkar, who builds individualized treatment plans based on your specific data — covering nutrition, supplements, hormones, and lifestyle modifications. This makes the testing actionable rather than simply informational. Bliss MD accepts HSA and FSA cards and provides detailed receipts for reimbursement, making functional medicine testing financially accessible for patients with health savings accounts. For anyone in Chicago or the Chicagoland area looking to understand their true health baseline and optimize for long-term vitality, Bliss MD's diagnostic offering is among the most thorough available in Illinois.
