Blood values for strength athletes
Blood values show your condition from the inside, past anything the mirror tells you. Training hard shifts some values for a while, muscle and liver markers among them. Look up a value and read its reference range. You also see when a result genuinely needs attention.

Eosinophils
Eosinophils are white blood cells involved in allergic reactions and the defence against parasites. As part of your complete blood count, they can offer clues about allergies or asthma.
Erythrocytes (RBC)
Your red blood cell count is a direct indicator of how effectively your body delivers oxygen to muscles and organs.
Estradiol (E2)
According to the NVKC, oestradiol, the main female sex hormone, is made from the male hormones testosterone and androgens, with the enzyme aromatase.
FSH (Follicle Stimulating Hormone)
Follicle-stimulating hormone (FSH) regulates sperm production and testicular function in men. It is produced by the pituitary gland and works alongside LH and testosterone.
Ferritin
Your ferritin value tells you how much iron you hold in reserve, because ferritin is the protein that stores iron, and in men that value points in two directions that are both often misread.
Folate (Folic Acid)
Folate measures vitamin B9 levels in your blood.
Free T3 (Triiodothyronine)
Free T3 is considered the most active thyroid hormone and may play an important role in men's metabolism, muscle maintenance, and energy levels.
Free T4 (Thyroxine)
Free T4 is the main hormone produced by the thyroid gland and may play an important role in men's metabolic rate, energy levels, and body composition.
Free Testosterone
Free testosterone is the unbound fraction that directly fuels muscle growth, energy, libido, and mental sharpness in men.
GGT (Gamma-Glutamyl Transferase)
GGT is a highly sensitive liver enzyme particularly relevant for men's health.
Glucose (Fasting)
Fasting glucose is a fundamental metabolic marker. Stable blood sugar supports energy, focus, and body composition for men.
HDL Cholesterol
Your HDL cholesterol tells you how much cholesterol is circulating in the particles that carry it back to your liver, and in men it is the value that responds most sharply to testosterone and at the same time the value least is said about.
HIV 1/2 Antibody + p24 Antigen
The HIV Combo test is a fourth-generation test that detects both HIV p24 antigen and HIV antibodies simultaneously.
HOMA-IR
HOMA-IR measures insulin resistance by calculating a score from fasting glucose and insulin levels.
Haptoglobin
A haptoglobin test measures the level of haptoglobin protein in your blood.
HbA1c (Glycated Hemoglobin)
HbA1c reveals your long-term metabolic control. Stable blood sugar supports sustained energy, focus, and body composition management.
Hematocrit
The hematocrit value describes how much of your blood consists of red blood cells, the cells that carry oxygen; at 0.48 l/l that is 48 percent, and the rest is fluid.
Hemoglobin
Hemoglobin is the engine behind your body's oxygen delivery.
Hemoglobin Electrophoresis
According to the NVKC, haemoglobin carries oxygen from the lungs to the organs, and according to Erfelijkheid.nl the causes of beta-thalassaemia are changes in the HBB gene, which mean not enough haemoglobin is made.
Hepatitis B Core Antibody
According to Thuisarts, in hepatitis B the liver is inflamed by a virus, and according to the RIVM, after an infection antibodies start forming against the core antigen (HBcAg) of that virus: anti-HBc.
Hepatitis B Surface Antigen
A Hepatitis B Surface Antigen (HBsAg) test detects the presence of HBsAg in your blood, which is one of the earliest indicators of a hepatitis B infection.
Hepatitis C Antibody
A Hepatitis C Antibody (anti-HCV) test detects antibodies produced by the immune system in response to the hepatitis C virus.
Holotranscobalamin
Holotranscobalamin measures the earliest marker of B12 deficiency. For men, early detection of B12 depletion may help preserve energy levels, cognitive sharpness, and nervous system health before symptoms develop.
Homocysteine
A homocysteine test is a blood test that measures how much homocysteine is in your blood. You do not need a referral from your GP.
