Blood work can sometimes help us understand what may be contributing to your symptoms or identify areas that warrant further investigation.

When clinically appropriate, laboratory testing may include:

- Iron & nutrient status- ferritin, iron studies, vitamin B12, folate and vitamin D

- Thyroid health — TSH and, when indicated, additional thyroid markers

- Blood sugar & metabolic health — fasting glucose, HbA1c and insulin

- Cardiovascular markers — cholesterol, LDL, HDL, triglycerides and ApoB

- General health markers — complete blood count (CBC), liver and kidney markers and electrolytes

- Celiac disease screening — appropriate antibody testing when celiac disease is suspected

- Inflammatory markers — such as CRP, when clinically indicated

- Hormonal testing — selected testing based on symptoms, life stage and clinical indication

- Other testing — additional laboratory investigations may be considered depending on your health history and symptoms
