Iodine
Iodine is essential for thyroid function, which regulates metabolic rate and energy availability during exercise. Adequate levels support consistent training performance.
Iron (Serum)
Serum iron indicates current iron availability for oxygen transport during exercise. Low levels can directly impact aerobic performance and recovery time.
Irregular Antibody Screening
An irregular antibody screening test detects unexpected antibodies in your blood that may react against foreign red blood cells. These antibodies can develop after transfusions, pregnancies, or immune stimulation and are important to identify for transfusion and pregnancy safety.
LDH (Lactate Dehydrogenase)
LDH is a tissue damage marker that active individuals should monitor carefully. Intense training causes temporary LDH elevations due to muscle breakdown, making it important to distinguish training-related changes from other causes for optimal recovery management.
LDL Cholesterol
LDL cholesterol management is important for active individuals who want to protect their cardiovascular system for long-term performance. Exercise can favourably influence LDL particle composition.
LDL/HDL Ratio
The LDL/HDL ratio is your LDL cholesterol divided by your HDL. Exercise tends to raise HDL, which lowers the ratio. A lower ratio is more favourable. Learn what your value can mean.
LH (Luteinizing Hormone)
LH is a critical pituitary hormone for active individuals, as it regulates sex hormone production that influences recovery, body composition, and training adaptation. Monitoring LH can help detect overtraining-related hormonal disruption.
Lactate
Lactate testing is essential for active individuals to determine training zones, assess aerobic capacity, and monitor the lactate threshold for performance optimisation.
Leukocyte Differential
A leukocyte differential test measures the relative proportions of different types of white blood cells in your blood. It provides a detailed breakdown of your immune cell populations, offering valuable insight into your immune system's function.
Leukocytes (WBC)
A leukocyte (white blood cell) count measures the total number of white blood cells in your blood. White blood cells are a crucial part of your immune system, defending your body against infections, viruses, and other harmful invaders.
Lipase
Lipase is essential for fat digestion and energy metabolism, making it relevant for active individuals who rely on efficient nutrient absorption. Monitoring lipase helps ensure the pancreas is functioning optimally to support high-fat recovery meals and performance nutrition.
Lipoprotein(a)
Lp(a) is a genetic cardiovascular risk factor that every active individual should know about. Understanding your inherent risk helps you make informed decisions about long-term cardiovascular health.
Liver Function Test (LFT)
A liver function test is essential for active individuals who place high demands on their body. Intense training, high-protein diets, and performance supplements are all processed by the liver, making regular comprehensive screening important for sustainable physical performance.
Lymphocytes
Lymphocytes are white blood cells central to your defence against viruses. This is relevant for active people, as intensive training and insufficient recovery can temporarily affect immune defence. A high count often fits a viral infection, while a low count can occur with stress or overload.
MCV (Mean Corpuscular Volume)
MCV (Mean Corpuscular Volume) measures the average size of your red blood cells. It is a key indicator used to classify different types of anemia and provides insight into the underlying cause of blood-related conditions.
Magnesium
Magnesium is critical for muscle contraction, energy metabolism, and recovery. Active individuals may have increased needs due to sweat losses and higher metabolic demands.
Magnesium (Intracellular)
Intracellular magnesium provides a true picture of magnesium availability for muscle contraction, energy production, and recovery — essential data for optimising performance.
Melatonin
Melatonin governs your sleep-wake cycle, and sleep is one of the most critical factors in physical recovery and performance. Monitoring melatonin can help identify whether your circadian rhythm supports optimal training adaptation.
Methylmalonic Acid (MMA) (Blood)
MMA Blood measures functional B12 activity at the cellular level. For active individuals, this test may detect subtle B12 insufficiency that could impair red blood cell production, oxygen transport, and muscle recovery before it shows on standard tests.
Methylmalonic Acid (MMA) (Urine)
MMA Urine is a non-invasive functional B12 assessment. For active individuals, this convenient test may help detect cellular B12 insufficiency that could impair oxygen transport, recovery, and endurance without needing a blood draw.
Microalbumin (Urine)
Microalbumin testing helps active individuals understand kidney stress related to intense training. Exercise-induced proteinuria can temporarily elevate urine albumin levels, so understanding your baseline is important for distinguishing normal training responses from potential kidney concerns.
Monocytes
Monocytes are the largest white blood cells and part of your complete blood count. They clear away damaged cells and pathogens and turn into macrophages that support tissue repair. For active people this matters, as a raised count can fit inflammation or recovery after an infection, while a low count is less common.
NT-proBNP
NT-proBNP can rise after intense endurance exercise. For active individuals, monitoring helps distinguish normal training responses from clinically significant cardiac stress.
Neutrophils
Neutrophils are the most common white blood cells and your first defence against bacterial infections. This matters for active people, as heavy training load can temporarily affect immune defence. A high count often fits an infection, inflammation or physical stress, while a low count can leave you more vulnerable.
