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.

17-OH Progesterone
17-OH Progesterone is a precursor steroid hormone essential for producing cortisol and androgens like testosterone. For men, monitoring this marker may provide insight into adrenal function and androgen production pathways.
ACTH (Adrenocorticotropic Hormone)
ACTH is a pituitary hormone that directs your adrenal glands to produce cortisol. For men, ACTH levels may reflect how your body handles physical and mental stress, directly influencing energy and hormonal balance.
AFP (Alpha-Fetoprotein)
An AFP (Alpha-Fetoprotein) test measures a key liver-related tumor marker in your blood. For men, AFP is particularly relevant for monitoring liver health, especially if you have risk factors such as hepatitis or heavy alcohol use. Take control of your health by understanding this important marker. This test alone cannot diagnose cancer and must be interpreted by a healthcare professional alongside other findings.
ALP (Alkaline Phosphatase)
In adults, alkaline phosphatase reaches the blood from two tissues. Those two are the bile ducts inside the liver and the skeleton. For anyone lifting heavy, the bone side is the relevant one. Bone is living tissue, continuously broken down and rebuilt. This enzyme is released during that rebuilding. A raised value is therefore not automatically a liver warning. This page covers the causes that belong with heavy loading. It also covers the order in which you rule them out.
ALT (Alanine Aminotransferase)
The ALT value measures alanine aminotransferase, the enzyme that sits mainly in the liver. In men the reference range runs to 45 u/l, higher than the 34 in women. That difference comes partly from muscle mass. A raised ALT result means liver cells are being damaged. For men who train there are three main routes: abdominal fat, alcohol and what is being taken. That third route is the least discussed and often the most decisive.
AST (Aspartate Aminotransferase)
Anyone training heavy reads a liver panel differently. The ratio between AST and ALT, the De Ritis ratio, is the most interesting number on your report, not AST alone. In most liver conditions ALT sits higher than AST. With muscle damage from a heavy squat or deadlift session, that ratio tips the other way. On older reports this enzyme is still called SGOT. This page covers the ratio, the pattern associated with alcohol, and what oral anabolics actually do to your liver values.
ASTO (Antistreptolysin O)
ASO testing identifies streptococcal antibodies that may indicate infection-related inflammation. Staying on top of infections supports uninterrupted vitality.
Active Vitamin B12
Active Vitamin B12 measures the bioavailable B12 your body can directly use. For men, adequate B12 may support energy levels, muscle function, and nervous system health. This test could offer a clearer picture than total B12 alone.
Albumin
Albumin reflects liver health and protein status, both fundamental for maintaining muscle mass, recovery capacity, and overall male vitality.
Albumin-to-Creatinine Ratio (ACR)
With a lot of muscle mass, a high-protein diet or creatine use, the creatinine in your urine can come out higher. Because the ratio divides by that creatinine, it belongs with the result, and is best read alongside your blood pressure.
Amylase
Amylase is a pancreatic enzyme important for men's digestive health. Men have higher rates of alcohol-related pancreatitis, making regular monitoring valuable.
Androstenedione
Androstenedione is a key precursor hormone that your body converts into testosterone. For men, monitoring this marker may offer direct insight into your testosterone production pathway and overall androgenic hormone balance.
ApoA1 (Apolipoprotein A1)
ApoA1 measures your heart-protective HDL function. Higher levels support cardiovascular strength and long-term vitality for men.
ApoB (Apolipoprotein B)
ApoB counts the atherogenic particles that drive heart disease. Knowing your number helps you take targeted action to protect cardiovascular health.
Basic Blood Count
A basic blood count measures three core values in your blood: hemoglobin, white blood cells and platelets. Together they say something about oxygen transport, immune defence and clotting. It is a simple baseline check, without the red-cell indices and white-cell differential of a complete blood count.
Basophils
Basophils are the rarest of the five cell types in your white blood count. In adult men the basophil blood value sits between 0 and 0.2 x10⁹/l. There is no separate male range for this value, unlike haemoglobin or ferritin. A low result is normal and calls for nothing. Basophils too high usually points to a reactive cause: a longer standing allergy or chronic inflammation. One raised measurement often falls inside the measurement variation of the assay. Below you can read when a rise is worth checking, and what a doctor does next.
Bicarbonate
Bicarbonate is key to maintaining acid-base balance, which supports muscle function and metabolic efficiency. Keeping your pH in check helps maintain peak physical performance.
Bilirubin (Direct)
Direct bilirubin is a liver marker particularly relevant for men who consume alcohol regularly or use supplements that may affect liver function. Monitoring this marker helps assess bile duct health and liver processing capacity.
Bilirubin (Indirect)
Indirect bilirubin is the part of your bilirubin that your liver has not yet processed. The value is not measured separately but calculated: your total bilirubin minus your direct bilirubin, in the same unit. That split helps to show where an abnormal total is coming from. This page explains what your indirect bilirubin result can mean.
Bilirubin (Total)
Total bilirubin is an essential liver marker for men's health. Alcohol intake, high-protein diets, and certain supplements commonly used by men can affect bilirubin levels. Regular monitoring helps identify potential liver issues early.
Blood Type + Rh
A blood type test determines your ABO blood group and Rh factor. Knowing your blood type is essential for safe blood transfusions, organ transplants, and pregnancy planning.
C-Peptide
C-Peptide reveals how effectively your pancreas produces insulin. Optimal insulin function supports energy, body composition, and metabolic performance.
CA 15-3
CA 15-3 is a glycoprotein marker associated with breast tissue that can also be relevant in men's health monitoring. As part of a comprehensive health check, understanding your CA 15-3 levels contributes to a complete picture of your wellbeing.
CA 19-9
CA 19-9 is a gastrointestinal marker that can be included in a comprehensive men's health panel. Tracking CA 19-9 over time gives you and your healthcare provider a clearer picture of your gastrointestinal wellbeing.
