Erythrocytosis is often discovered incidentally on a routine blood test. In Canada, up to 4% of ambulatory men and 0.4% of ambulatory women have erythrocytosis, based on hemoglobin levels greater than 165 g/L or 160 g/L, respectively.
Small red blood cells are a common finding on a routine blood count and can easily be overlooked. In 2021, 24.3% of the global population across all ages had anemia, equal to 1.92 billion cases, and dietary iron deficiency was the leading cause of years lived with disability due to anemia.
MCH is one of the quiet numbers on a complete blood count. Most people scroll past it on the way to hemoglobin. That is a mistake, because in iron deficiency anemia a low MCH can turn up more often than the better-known marker of small red cells.
Haptoglobin is not part of a standard blood count; most people meet it when a doctor is investigating anemia, jaundice or unusual results.
Anaemia, which is diagnosed from a low hemoglobin concentration, is remarkably common. According to the Global Burden of Disease Study, the global prevalence of anaemia across all ages in 2021 was 24.3%, which corresponds to 1.92 billion people.
MCHC is the red cell index most people skim past on a complete blood count. When it is flagged high, the first suspect is often the sample rather than the patient: haematology laboratories commonly use MCHC as an analytical control, because a high value tends to point to an artefact.
An RBC blood test counts the red blood cells in a sample of your blood. It is a standard part of the complete blood count (CBC), and when the result comes back with an “H” or “L” flag, the natural question is whether something is wrong.
The MCV blood test is routinely reported as part of the complete blood count (CBC), one of the most common blood panels in healthcare.
When a routine blood report mentions a mchc blood test low result, it can be difficult to know what to make of it. MCHC, or mean corpuscular hemoglobin concentration, describes the average concentration of hemoglobin within red blood cells.
EPO in athletes sits at a contested intersection of sports medicine, clinical diagnosis, and anti-doping science. Endurance athletes speak of “natural EPO elevation” from altitude camps as a badge of physiological adaptation.
In my clinical practice, the evaluation of anemia often focuses primarily on the complete blood count (CBC) and ferritin levels.
Bilirubin in athletes is observed more frequently than in the general population. In my clinical practice, isolated mild elevations are typically benign and seldom require intervention.
Some of my patients may have heard of the protein haptoglobin, but it remains relatively unfamiliar—and even when recognized, it is often misunderstood.
In my experience, athletic patients are often well-informed about nutrition and vitamins. They are typically interested in tracking their biomarkers, and quite often they are particularly concerned about things like iron levels.
In my practice, most athletes focus on hemoglobin and ferritin, with fewer paying attention to hematocrit. These markers are important, but they mainly describe the current state rather than where things are heading.
When I see athletic patients, they are often highly aware of anemia and iron deficiency, and may become concerned when they notice that their hemoglobin is unexpectedly low on routine blood tests.
In my physically active patients, one of the most important basic laboratory tests is the basic or complete blood count, with particular attention given to red blood cell–related parameters, as these are closely linked to oxygen transport and, by extension, physical performance.
Hematocrit in athletes is a parameter included in both basic and extended blood counts. It has been measured in almost every individual at some point, and clinicians encounter it constantly in everyday practice.
Hemoglobin levels in runners are often lower than expected, and this frequently causes confusion when reviewing routine blood tests.
Mean corpuscular volume represents one of the most fundamental yet frequently misunderstood markers in athletic blood work interpretation.
