Low basophil levels, a condition called basopenia, may indicate a suppressed immune system or the presence of other underlying health issues. Basophils are a type of white blood cell involved in immune responses, especially inflammation and allergic reactions. Basopenia can result from acute infections, severe allergies, or chronic stress. In some cases, low basophil counts may also be seen with long-term steroid use or hyperthyroidism. While low basophil counts are often transient and not dangerous on their own, persistent basopenia warrants further medical evaluation to identify any underlying conditions that may need attention.

Low Mean Corpuscular Hemoglobin Concentration (MCHC) levels typically indicate anemia, where red blood cells have less hemoglobin than normal. This can result in symptoms such as fatigue, weakness, and pale skin. Low MCHC is commonly associated with iron-deficiency anemia or chronic blood loss. It can also be caused by conditions that affect red blood cell production or lifespan. Treatment depends on the underlying cause and may include iron supplementation, dietary changes, or addressing chronic conditions. Regular blood tests can help monitor MCHC levels and guide treatment decisions.

Testosterone levels vary significantly by age and are crucial for many physiological functions, including muscle mass, bone density, and sexual health. For men, normal testosterone levels generally peak during adolescence and early adulthood and begin to decline gradually with age. In young adult males, normal testosterone ranges from 300 to 1,000 ng/dL. For men over 50, levels tend to be lower, around 200 to 800 ng/dL. Low testosterone can lead to symptoms like fatigue, low libido, and decreased muscle mass. Understanding your age-appropriate testosterone levels through a blood test is key to addressing potential health issues.

A faecal calprotectin test measures the level of calprotectin, a protein released by white blood cells, in your stool. High levels typically indicate inflammation in the intestines, which can be a sign of conditions like Crohn’s disease or ulcerative colitis. Low levels suggest that intestinal inflammation is unlikely, making conditions such as irritable bowel syndrome (IBS) more probable. Understanding whether calprotectin levels are high or low helps doctors distinguish between inflammatory bowel diseases (IBD) and non-inflammatory conditions, guiding appropriate treatment plans.
