Test ID: SB-642 | Saliva 4-Point Cortisol + Blood Spot Thyroids and CardioMetabolic
Feeling constantly tired, stressed, or struggling with low energy, poor sleep, or weight changes? These symptoms are often linked to thyroid imbalance, stress response, or blood sugar and metabolic issues. This at-home Thyroid & CardioMetabolic Test Kit helps you understand what may be affecting your body so you can take informed next steps.
Suitable for women, men, adults, and children, this advanced profile provides a clear overview of thyroid function, cortisol rhythm, blood sugar balance, inflammation, and heart health. It is ideal for anyone looking for answers to symptoms such as fatigue, slow metabolism, low motivation, mood changes, stress-related issues, or possible thyroid dysfunction.
This advanced profile measures 13 key markers linked to thyroid health, stress response, and cardiometabolic function. Saliva testing includes Cortisol 4-point C(x4) to assess your daily stress pattern. Blood spot testing includes Thyroid Stimulating Hormone (TSH), Free T3 (FT3), Free T4 (FT4), Thyroid Peroxidase Antibodies (TPOab), Insulin (IN), Thyroglobulin Antibodies (Tgbn), Hemoglobin A1c (HbA1c), High-Density Lipoprotein (HDL), Triglycerides (TG), Total Cholesterol (CH), High-Sensitivity C-Reactive Protein (hsCRP), and Total T4 (TT4).
By analysing these markers, this test can help identify thyroid dysfunction, cortisol imbalance, insulin resistance, blood sugar issues, inflammation, and cardiometabolic risk factors. It provides valuable insight for anyone considering changes to their lifestyle, nutrition, or overall health strategy.
The kit is easy to use at home. Collect your samples from the comfort of your home and post them to our laboratory. Your results will be available within 3–5 working days after the laboratory receives your sample. You will receive a clear report with your results presented in graphics and numbers, along with professional comments from a Hormone Specialist PhD doctor, including guidance on what to do next.
The test is suitable for adults and children. The kit includes the laboratory fee, with no additional laboratory cost or tax. Customers are responsible for shipping their samples to the laboratory. The test must be used within 12 months of the purchase date.
