Bloodworks Sport
Sport & recoveryA focused sports panel with the markers that matter for performance and recovery: iron status, electrolytes, muscle recovery (CK), metabolism and the hormones behind recovery and balance. All-in, including blood draw and collection costs.
View all 19 biomarkers
Blood count and iron3 biomarkers
Haemoglobin (Hb)
Oxygen transport in the blood.
Why we measure this
Anaemia is an underestimated cause of lost performance and fatigue in athletes.
Iron
Essential for oxygen transport.
Why we measure this
Iron deficiency is common in athletes, particularly women and endurance athletes.
Ferritin
Iron stores; a sensitive indicator of iron status.
Why we measure this
Ferritin often drops before haemoglobin does, revealing a developing iron deficiency early.
Electrolytes and kidney6 biomarkers
Sodium
Electrolyte; fluid balance and nerve function.
Why we measure this
Fluid-balance disturbances affect endurance and recovery.
Potassium
Electrolyte; heart conduction and muscle function.
Why we measure this
Potassium is essential for muscle and heart function during exercise.
Urea
Protein breakdown product; kidneys and hydration.
Why we measure this
With creatinine it gives insight into hydration and protein load during intensive training.
Creatinine
Kidney function; muscle breakdown product.
Why we measure this
Sometimes higher in athletes due to muscle mass; we combine it with eGFR for correct interpretation.
eGFR
Estimated kidney filtration rate.
Why we measure this
Monitors kidney function, also with high protein and supplement intake.
Magnesium
Muscle function and recovery.
Why we measure this
Intensive training raises magnesium needs; a deficiency gives cramps, poor sleep and slow recovery.
Muscle and recovery3 biomarkers
AST
Liver and muscle enzyme; cell damage.
Why we measure this
With ALT and CK a measure of muscle load and recovery.
ALT
Liver enzyme.
Why we measure this
Separates liver from muscle load within the recovery picture.
Creatine kinase (CK)
Muscle damage marker; raised after intensive training.
Why we measure this
CK reflects muscle breakdown and recovery; it helps assess whether load and rest are in balance.
Energy and metabolism3 biomarkers
Glucose (fasting)
Blood sugar after fasting.
Why we measure this
Gives insight into energy metabolism and metabolic risk.
HbA1c
Average blood sugar over ~3 months.
Why we measure this
Shows longer-term sugar status, useful with carbohydrate-rich sports nutrition.
TSH
Pituitary hormone driving the thyroid.
Why we measure this
The thyroid drives metabolism and energy; an abnormality explains unexplained fatigue or weight change.
Hormones and recovery2 biomarkers
Testosterone
Hormone with a role in muscle building and recovery.
Why we measure this
A sustained high training load can suppress testosterone; measuring it gives insight into your recovery capacity and balance.
Cortisol
Stress hormone; an indicator of overtraining.
Why we measure this
Chronically raised cortisol can point to overtraining or insufficient recovery, often before you notice it.
Vitamins2 biomarkers
Vitamin D (25-OH)
Bone and muscle function.
Why we measure this
Vitamin D plays a role in muscle strength and bone density; in athletes a deficiency is associated with more injuries.
Vitamin B12
Energy metabolism and blood production.
Why we measure this
B12 is crucial for energy and oxygen transport; deficiencies are more common in plant-based athletes.

Doctor comment
Your magnesium and vitamin D are markedly reduced. This can contribute to fatigue, muscle cramps and lower immunity. Supplements are generally available over the counter in the Netherlands. At your levels, however, we advise read more ›
Experiences
What customers say
Vanuit de sportschool geattendeerd op Bloodworks en heel tevreden. Bloedonderzoek online besteld en kon direct terecht bij een lab in de buurt. Kreeg het labformulier per e-mail en na het prikken de resultaten met uitleg ontvangen. Kom hier zeker vaker terug!
Ik heb eerder onderzoeken laten uitvoeren door andere organisaties, maar Bloodworks steekt daar met afstand bovenuit. De snelle service, het persoonlijke contact en de transparantie hebben ervoor gezorgd dat ik al mijn vervolgonderzoeken hier laat uitvoeren.
Na geregeld duizelig te voelen ben ik langs geweest bij Bloodworks voor een bloedtest, snelle service en super snel uitslag gekregen! Advies gekregen van de specialisten om een aantal waardes aan te vullen, en daadwerkelijk geen last meer van mijn klachten. Super dankbaar, vakkundig en bekwaam.
