Your 40s are a crucial decade for understanding what's happening in your body. As hormones begin to shift and metabolic changes occur, the right blood tests can provide invaluable insights into your health and help you take proactive steps to feel your best.
These five essential blood tests can help identify hormonal imbalances, metabolic dysfunction, and inflammation before they become serious health issues. Early detection means better outcomes and more treatment options.
Your thyroid function can be affected and worsen weight gain, fatigue and metabolic health. If you are suffering from any of these symptoms you should rule out hypothyroidism or Hashimoto's.
Primary screening test for thyroid function
Active thyroid hormones that affect metabolism
Can indicate stress or conversion issues
Screens for autoimmune thyroid conditions
This test evaluates your insulin resistance and metabolic function. High insulin levels can indicate prediabetes and metabolic dysfunction. This can lead to fat loss resistance and an increase in inflammation markers.
These are markers of systemic inflammation that are linked to increase in cardiovascular disease and metabolic dysfunction. Include CRP and Omega 3 levels to check for potential chronic inflammation.
Measures general inflammation in the body and cardiovascular risk
Assesses anti-inflammatory fatty acid status and heart health
Check your estradiol, progesterone, testosterone, DHEA-S, FSH - this is key because to assess peri/menopause we need to correlate these levels with your symptoms. Low estrogen can produce insulin resistance, lipid metabolism, cardiovascular health, bone health, muscle building issues.
Primary estrogen hormone
Balances estrogen effects
Affects energy and libido
Adrenal hormone precursor
Indicates ovarian function
FSH above 25 is strongly correlated with low estrogen levels. Make sure you check these levels and correlate them with your symptoms for accurate assessment.
High levels of homocysteine indicate inflammation and increased cardiovascular risk. Can signal issues with detoxification and metabolism.
Getting these tests is just the first step. The real value comes from understanding your results and working with a healthcare provider who specializes in women's health and hormone optimization.
Remember: optimal ranges may be different from "normal" lab ranges. What matters is how you feel and function, not just whether you fall within the reference range.
