What Is Infection and Inflammation?
Infection occurs when viruses, bacteria, fungi, or parasites invade the body and begin to multiply. The immune system responds to fight off the invader, which often leads to inflammation—the body’s protective response.
Inflammation can be:
Acute: Short-term, like swelling or redness after an injury or infection.
Chronic: Long-term, potentially damaging, and linked to conditions like arthritis, heart disease, and autoimmune disorders.
While symptoms like fever, fatigue, or pain may suggest an issue, they’re not always specific. That’s where blood tests become essential.
What Causes Infection and Inflammation?
There are many common causes of infection and inflammation, including:
Viral infections (e.g. flu, COVID-19)
Bacterial infections (e.g. urinary tract infections, pneumonia)
Autoimmune conditions (e.g. rheumatoid arthritis, lupus)
Allergies and chronic diseases
Injuries or post-surgical healing
Chronic conditions (e.g. inflammatory bowel disease)
Left unchecked, chronic inflammation can lead to serious health problems—making early detection critical.
The Best Blood Tests to Detect Infection and Inflammation
At Mybloods, we offer a range of targeted blood tests that can help spot infection or measure inflammation levels in the body. The most commonly recommended include:
1. CRP (C-Reactive Protein) Test 
Measures the level of CRP, a protein that increases with inflammation.
Ideal for detecting acute and chronic inflammation. Common in conditions like infections, arthritis, and cardiovascular disease.
2. ESR (Erythrocyte Sedimentation Rate) Test 
Assesses how quickly red blood cells settle at the bottom of a test tube. A faster rate can indicate inflammation in the body. Useful for diagnosing autoimmune diseases or ongoing infections.
3. Full Blood Count (FBC) 
Looks at white blood cells, red blood cells, and platelets. High white blood cell count often indicates infection. Can highlight signs of inflammation, anaemia, or immune response.
4. Procalcitonin Test
A marker that increases in response to bacterial infections. Helps distinguish bacterial infections from viral causes.
5. Ferritin Test
Ferritin is not just related to iron storage—it also rises in inflammation. Useful in identifying chronic inflammation.
