What Blood Tests Should I Get Done Annually?

What Blood Tests Should I Get Done Annually?

 During January or February each year, I head off to get my annual blood test done. Now that I am over 40 (and I am passionate about preventative healthcare), this yearly check in is a form of self care. It allows me to have a check in with my health and also compare my results to the previous year to see if I can note any trends in my results. Plus I also compare my results to specific reference ranges (which are very different to "normal" reference ranges as my aim is to thrive in life (not live the life of an average Australian - because in Australia, about 65% of people are currently overweight or obese, 81.4% of people have at least one long-term health condition, 49.9% have at least one chronic condition) "Normal" is definitely not healthy anymore.

I also like to get annual blood tests done so I can also use this information to see how my body is responding to diet, lifestyle, nutritional and herbal interventions. Here is what I get checked every year. Please also remember that this list is specific to me and my personal health and family history. Everyone will have a different set of blood tests which would be great to get done each year. 

Thyroid Studies

Thyroid hormones play a crucial role in regulating metabolism, energy levels, and overall well-being. Tests such as TSH (thyroid-stimulating hormone), T3 (triiodothyronine), and T4 (thyroxine) help assess thyroid function. Imbalances in thyroid hormones can impact energy levels, mood, and weight, making thyroid testing essential for a comprehensive health assessment. I have a strong family history of thyroid conditions and have seen how misdiagnosis (and late diagnosis) has impacted the health of family members. I like to get TSH, T4, T3 and thyroid antibodies checked annually. A TSH over 2.5 is a cause for concern to me (once again wanting to work within optimal parameters). 

Iron Studies plus CRP

Iron deficiency anemia is the most common cause of anemia worldwide plus is a very common deficiency in menstruating women and so a yearly screen helps to identify any issues with iron stores. I include CRP as it is a marker of chronic inflammation which linked to various health issues, including cardiovascular disease and autoimmune conditions. Plus increased levels of CRP may affect other test results such as serum ferritin, as it too is an acute phase protein, and test levels increase with the presence of inflammation in the body, which is used to assess population Iron deficiency. Monitoring inflammatory markers annually provides insights into overall inflammatory status.

Vitamin D

Vitamin D plays a crucial role in bone health, immune function, and overall well-being. Deficiencies in vitamin D are common, especially in regions with limited sunlight. Annual testing helps ensure adequate vitamin D levels, supporting bone health and reducing the risk of conditions associated with deficiency.

Cholesterol Studies

A lipid panel measures cholesterol levels in your blood, including low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides. Elevated LDL cholesterol is a risk factor for heart disease, while higher levels of HDL cholesterol are considered protective. Regular monitoring of lipid levels helps assess cardiovascular health and guides preventive measures.

Metabolic Parameters - HbA1c, fasting glucose, fasting insulin

I have a family history of diabetes and previous tests have revealed elevated insulin (with normal blood glucose). I usually refer myself privately for this test as I find it difficult for a GP to refer for this marker. An insulin test measures the insulin levels in your blood. It is used to diagnose hypoglycemia, insulin resistance, and other health issues. This is a great test for those interested in preventative health as elevated levels of insulin can be a precursor to developing chronic diseases. Insulin resistance is the main feature of ‘metabolic syndrome’, which is a set of factors that link excess fat around the waist to increased risk of cardiovascular disease and stroke. Elevated blood insulin levels over time can have harmful effects, such as hardening of the arteries, high blood pressure, increased risk of blood clots, elevated uric acid (gout) and PCOS.


Both of these are important for energy production and nervous system health. Laboratory tests for folate and vitamin B12 are essential for the diagnosis of a deficiency of these vitamins, and for the investigation of some forms of anaemia.

Complete Blood Count (CBC) 

A CBC is a standard blood test that assesses the number and health of various blood cells, including red blood cells, white blood cells, and platelets. This test can help detect conditions such as anemia, infections, and certain blood disorders, providing a broad overview of your overall health.

Comprehensive Metabolic Panel:

 A comprehensive metabolic panel (CMP) is a routine blood test that measures 14 different substances in a sample of your blood. It provides important information about your metabolism (how your body uses food and energy) and the balance of certain chemicals in your body.

Best Time to Test?

Now it is one thing to get blood tests done and another ting to get them done at the right time. For women in their fertile years, I usually recommend blood tests are done fasted (even if this is not required), during week three of your menstrual cycle, no supplements,  no high intensity exercise or alcohol in the previous 48 hours and well rested if possible. I know the chances of all these factors being taken into consideration is slim but this what I usually suggest to get a nice accurate test result!

Now I used to visit my GP for this referral but have found some push back lately. I totally understand this as GP's are often audited for their referrals so now I use Iscreen or Instantscript so I choose what needs to be done myself. I am out of pocket for these but I see this as an investment in my health and I save up for this yearly cost. Once I receive my results, I run the figures through a body optimisation calculator which gives me optimal blood test parameters (not just conventional ones)
