Chronic infections and inflammatory diseases involve persistent immune system activation that affects multiple body systems including nutrient metabolism and mineral absorption. These conditions are caused by ongoing bacterial infections, autoimmune responses, or prolonged tissue inflammation that triggers the release of inflammatory cytokines like interleukin-6 and tumor necrosis factor-alpha. The Iron, Serum with TIBC test is the most important test for diagnosis because it reveals how inflammation affects iron metabolism and helps distinguish inflammatory iron changes from true deficiency.

Chronic infections and inflammatory diseases are caused by persistent bacterial infections like tuberculosis or Helicobacter pylori, autoimmune conditions where the immune system attacks healthy tissue, or prolonged inflammatory responses from conditions like rheumatoid arthritis and Crohn disease. These conditions trigger continuous release of inflammatory proteins called cytokines, including interleukin-6 and tumor necrosis factor-alpha, which affect how your body processes nutrients and minerals. The ongoing inflammation creates a cycle where the immune system remains activated for months or years, leading to changes in blood chemistry that can be detected through testing.
The Iron, Serum with TIBC test is the most important test for chronic infections and inflammatory diseases because it detects how inflammation affects your body's iron metabolism. During chronic inflammation, your immune system deliberately lowers iron levels in your bloodstream to starve bacteria of this essential nutrient while also reducing iron absorption in your intestines. This test measures both your serum iron and total iron-binding capacity, creating a pattern that helps distinguish between inflammation-related iron changes and true iron deficiency anemia. The ratio between these values reveals whether low iron is your body's defensive response to infection or a separate nutritional problem requiring different treatment.
You should get tested if you experience persistent fatigue that lasts more than a few weeks, unexplained fever or night sweats, ongoing joint pain or stiffness, digestive problems like chronic diarrhea or abdominal pain, or wounds that heal slowly. Testing is particularly important if you have a known autoimmune condition, recurrent infections, or inflammatory bowel symptoms that interfere with daily activities. Early testing helps identify the inflammatory response before it leads to complications like anemia or malnutrition, allowing for timely intervention.

What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
