Panel content

Hormones


DHEAS: A precursor to sex hormones, involved in energy and muscle recovery. Low levels can suggest overtraining or the need for recovery optimization. It is a general marker of adrenal function, and low levels might be associated with fatigue and a reduced ability to cope with training stress.  


Testosterone, SHBG, Free Testosterone, FAI, Oestradiol, LH, FSH, Progesterone: Track these hormones for optimal energy levels, muscle building/repair, libido, and motivation. Imbalances can lead to fatigue, injuries, and performance declines. In females, these also regulate the menstrual cycle, crucial for adaptation to training.  


Prolactin: High levels can suppress sex hormones, impacting performance. It is important to monitor hormonal imbalances or medication use.  
TSH, FT4, FT3: Assess thyroid function, which regulates metabolism, energy, and recovery. Imbalances have a significant impact on an athlete's ability to perform and recover.  


Metabolic Health, Inflammation, & Recovery


Creatinine Kinase (CK), LDH, Urea, Creatinine, eGFR, Sodium, Chloride: Assess muscle breakdown, kidney function, and electrolyte balance to indicate overtraining, dehydration, or kidney issues, all of which hamper performance and recovery.  


hsCRP: Tracks general inflammation. Chronic elevation can signal overtraining, an underlying infection, or a need for more recovery.

 
Magnesium, Triglycerides, Cholesterol, HDL, LDL, Non-HDL, Apolipoprotein B, HDL % of Total Cholesterol: Assess cardiovascular health, crucial for long-term athletic performance and overall well-being. Understanding these markers allows for targeted interventions to promote healthy energy delivery and reduce risk factors.  


Liver Function


ALT, AST, ALP, Bilirubin, GGT, Albumin, Globulin, Total Protein: Evaluate overall liver health. The liver plays a vital role in detoxification, protein production, and metabolism - all of which impact an athlete's ability to process nutrients and recover.  


Iron & Vitamin Status


Iron, Ferritin, UIBC, TIBC, Transferrin Saturation, Active B12, Vitamin D, Folate: Ensure optimal levels of nutrients essential for oxygen transport, energy, and cellular function. Deficiencies directly hinder performance and recovery.  


Blood Cells


Haemoglobin, Haematocrit, RBC, MCV, MCH, MCHC, RDW, White cell count, Neutrophils, Lymphocytes, Eosinophils, Basophils, Platelet count: Assess overall blood cell health, oxygen delivery, and immune system function. Changes can indicate infection, anemia, allergies, or overtraining, directly impacting performance and the body's capacity to handle training loads.
