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.
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.
Complete Blood Count (CBC)
A complete blood count is the broadest basic panel available. From one tube a cell counter counts your red blood cells, your white blood cells and your platelets, and determines the amount of haemoglobin. If you steer on energy, performance and recovery, the question is not whether there is an arrow. The question is which values genuinely say something and which are noise. That distinction is workable with this panel, provided you read the pattern rather than individual numbers.
Coombs Test (Indirect)
The indirect Coombs test screens for unexpected antibodies in your blood that may react against red blood cells. It is an important test for transfusion safety and prenatal care.
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. A raised count is often seen with allergic complaints or a parasitic infection, while a low count is usually not a concern.
Erythrocytes (RBC)
Your red blood cell count is a direct indicator of how effectively your body delivers oxygen to muscles and organs. For men focused on vitality and physical performance, monitoring erythrocytes helps ensure you are operating at full capacity.
Haptoglobin
A haptoglobin test measures the level of haptoglobin protein in your blood. Haptoglobin binds to free hemoglobin released from damaged red blood cells, and its levels can help assess whether red blood cells are being destroyed faster than normal.
Hematocrit
In men, hematocrit is the value that shows first when red cell production changes. It describes how much of your blood consists of red cells. Testosterone actively drives that production. That is exactly why the male reference band sits above the female one. It is also why this value is monitored as standard under testosterone therapy. A raised hematocrit is not a diagnosis in itself. The question is always what pushes it up: dehydration, smoking, sleep apnoea, altitude or a hormonal cause.
Hemoglobin
Hemoglobin is the engine behind your body's oxygen delivery. For men focused on strength, endurance, and daily energy, tracking hemoglobin ensures your blood is fuelled for action and your vitality stays on point.
Hemoglobin Electrophoresis
Hemoglobin electrophoresis is a laboratory technique that separates and identifies different types of hemoglobin in your blood. It is primarily used to detect hemoglobin variants and diagnose inherited blood disorders such as sickle cell disease and thalassemia.
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.
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)
The leukocyte count tallies your white blood cells, the ones that tackle infection and inflammation. Unlike haemoglobin or ferritin, this number has no separate male and female reference. At the laboratory that runs the test both use 4.3 to 10.0 x10^9/L. What does stand out in men is which lifestyle factors shift the number in practice. Heavy strength training, chronic sleep debt, sustained stress and above all smoking are the four. Rule those out before you think of anything else.
Lymphocytes
Lymphocytes are white blood cells central to your defence against viruses and to immune memory. As part of your complete blood count, they show how your immune system responds. A high count often fits a viral infection, while a low count can occur with stress, certain infections or medications.
MCH (Mean Corpuscular Hemoglobin)
MCH is the average amount of haemoglobin in one red blood cell. Read alongside MCV and haemoglobin, it narrows down why a blood count is abnormal rather than just showing that it is. Learn what your value can mean.
MCHC (Mean Corpuscular Hemoglobin Concentration)
MCHC is the average concentration of haemoglobin inside your red blood cells. It varies least of the three red cell indices, which is precisely why an abnormal value is worth taking seriously. Learn what your value can mean.
MCV (Mean Corpuscular Volume)
MCV is the average volume of a single red blood cell, expressed in femtolitres, and the reference range shown on this page runs from 80 to 100 fl. An MCV value of 89 sits squarely in the middle of that range and is an entirely ordinary result for an adult man; in the 20 to 29 age group the median is 89.9 fl, measured at a single South Korean hospital. If your MCV is too low, below 80 fl, your red cells are smaller than average and iron deficiency is the first question. Above 100 fl they are larger instead. One thing to hold on to: a normal MCV does not rule out a deficiency.
Monocytes
Monocytes are the largest white blood cells. They help sustain chronic inflammation. Smoking is the one lifestyle factor with a clearly measured effect on this number. A persistently raised count fits a longer-running inflammatory process. One raised measurement says nothing about that. On this page you can read what your monocyte value does and does not say. You can also read why this number is not a cardiovascular risk score.
Neutrophils
Neutrophils are the most common white blood cells and your first defence against bacterial infections. As part of your complete blood count, they show how your immune defence is doing. A high count often fits an infection or inflammation, while a low count can make you more vulnerable to infections.
Platelets (Thrombocytes)
Your platelet count tells you how many platelets are circulating in your blood. Platelets are the fragments that seal a small wound and stop bleeding. For adults that band sits between 150 and 400 x10⁹/l. That range is the same for men and women, unlike haemoglobin. Alcohol, inflammation, iron deficiency and recent surgery all move the number. Aspirin and ibuprofen do something different: they change how platelets work, not how many there are. This page explains what a high or low result can mean for a man. Reference values differ between laboratories, so your own report is what counts.
RDW
RDW shows how much your red blood cells vary in size and can give an early clue before other values change. For men, a raised RDW may point to a shortage of iron, vitamin B12 or folate that can affect energy and vitality. Your doctor reviews it together with your hemoglobin and MCV.
Reticulocytes
A reticulocyte count measures the number of young, immature red blood cells in your blood. It reflects how actively your bone marrow is producing new red blood cells and is a valuable indicator of bone marrow function.
