In this article, we discuss how to obtain accurate pathology tests. Whilst this article is not meant to serve as a diagnostic tool, it may help you understand why pathology tests are useful and how to get the most reliable test results.
Longer-term patterns of pathology results can provide a holistic picture of your overall health and the progression of underlying issues. We monitor key nutrients that provide warning signs of underlying imbalances that, if left unchecked, can contribute to ill health and disease. One abnormal blood marker in pathology tests doesn’t always mean there is an issue. Pathology tests should always be considered in conjunction with your symptoms and physical appearance and discussed with your practitioner so that the context and relevance of your results can be determined.
WHAT PATHOLOGY TESTS ARE MOST USEFUL?
Your GP or naturopath can arrange pathology testing for you. Your healthcare practitioner will determine the exact pathology tests you require. The following tests may be useful for active individuals as a good starting point.
*Full blood count and haematology—these examine your white and red blood cells and provide a general picture of your immune system and overall health.
*Liver function tests (LFTs) provide some clues as to how your liver is working and whether it is under stress.
*Electrolytes– potassium, sodium, chloride and other key electrolytes required for sports performance and optimal health.
*Fasting blood glucose- is a general marker that indicates how well your body is modulating your blood sugar. Issues with blood sugar stabilisation may cause symptoms such as sugar cravings, frequent urination, fatigue, and energy drops after meals.
*Insulin helps us understand how hard your pancreas is working to maintain normal blood sugar levels. This marker is useful if you have a family history of diabetes or have been prediabetic or ” insulin resistant” in the past. Insulin resistance is more common as we age. In women, it is more common over the age of 40 and in perimenopause and postmenopause.
*C- reactive protein (CRP) is an inflammatory marker. CRP is useful when interpreted in conjunction with iron studies. Iron storage may be impacted by states of high inflammation.
*Iron studies- provide information on your iron storage (ferritin), the protein carriers for iron (transferrin), and how effectively your body is saturating these carriers and transporting iron around your body (transferrin saturation).
*Thyroid hormones- TSH, T3 and T4 provide information on how your thyroid is functioning and can be an early warning sign of autoimmunity and nutrient deficiencies such as iodine, selenium, tyrosine and zinc.
*Vitamin B12 (active and inactive) is also suggested for plant-based patients or athletes who infrequently consume red meat.
* Nutrients—If you experience mental health issues (especially seasonal sadness/ low mood), autoimmunity, frequent colds or infections, bone health issues, hormonal issues, or are peri or postmenopausal, nutrients such as vitamin D, copper, and serum zinc may also be useful markers.
Tests may be repeated every few months to ensure a patient is responding to treatment and maintaining a balanced state of health.
How to get the most accurate pathology tests
Prepare for your blood tests.
DO
- Fast for 12 hours (have dinner and then postpone breakfast until after your blood draw).
- Sip water the morning of your blood test so you are not dehydrated when you have your test. Dehydration can make your veins more difficult to locate.
- Take a snack to have immediately after your blood draw.
AVOID
- Strenuous exercise for a minimum of 24 hours. Ideally, at least 48 hours if possible. This includes running, cycling, or strength training. Most patients find it easiest to do a blood test the morning after a rest day. A walk or gentle exercise is ok before a blood draw.
- If you plan to check your iron levels, avoid a blood test when you are unwell or have an infection. An infection may influence your test results. Wait until you are feeling better before having your iron test.
- Stop supplements, including iron or other vitamin tablets or powders, for 24-48 hours before your blood tests.
We use a number of pathology collection centres across Australia including Clinical Laboratories, Dorevitch, and Nutripath to obtain accurate pathology results. We may also recommend functional testing such as detailed heavy metal and mineral testing and comprehensive microbiome tests during our clinical assessments.
