A decreased ESR (Erythrocyte Sedimentation Rate) can occur due to various physiological and pathological conditions. Here’s a concise overview:
🔽 Causes of Decreased ESR
🧬 Blood-related Conditions
– Polycythemia vera: Increased number of red blood cells slows sedimentation
– Sickle cell disease: Abnormal RBC shape prevents stacking (rouleaux formation)
– Hereditary spherocytosis: Spherical RBCs resist sedimentation
– Acanthocytosis: Spiked RBC membranes disrupt settling
🧫 Protein & Plasma Abnormalities
– Hypofibrinogenemia: Low fibrinogen reduces RBC aggregation
– Hypogammaglobulinemia: Low immunoglobulin levels affect plasma viscosity
– Hyperviscosity syndrome: Thick plasma slows RBC movement
❤️ Cardiovascular & Systemic Conditions
– Congestive heart failure: Alters blood flow and plasma composition
– Liver disease: Affects plasma protein synthesis
💊 Medications
– NSAIDs (e.g., aspirin, ibuprofen)
– Corticosteroids
– Antibiotics and immunosuppressants (e.g., penicillamine, quinine)
🚬 Lifestyle Factors
– Smoking
– High-dose aspirin therapy
– Certain dietary patterns
🧪 Clinical Note
A low ESR is usually not a cause for concern on its own. However, it may help identify underlying conditions when interpreted alongside other tests.
The normal values of ESR (Erythrocyte Sedimentation Rate) vary based on age and sex. Here's a quick reference: 📊 Normal ESR Values A) Men 1. < 50 years (0 – 15) 2. ≥ 50 years (0 – 20) B) Women 1. < 50 years (0 – 20) 2. ≥ 50 years (0 – 30) C) Children (0 – 10) D) Newborns (0 – 2) These values aRead more
The normal values of ESR (Erythrocyte Sedimentation Rate) vary based on age and sex. Here’s a quick reference:
📊 Normal ESR Values
A) Men
1. < 50 years (0 – 15)
2. ≥ 50 years (0 – 20)
B) Women
1. < 50 years (0 – 20)
2. ≥ 50 years (0 – 30)
C) Children (0 – 10)
D) Newborns (0 – 2)
These values are based on the Westergren method, which is the most commonly used technique.
