MCHC Test in Chennai

What is an MCHC Blood Test?

The MCHC test in blood calculates the average concentration of haemoglobin within a given volume of packed red blood cells, expressed as grams per decilitre (g/dL). It forms a key part of the complete blood count (CBC) and provides insights into red blood cell quality and oxygen-carrying capacity.

Why is the MCHC Blood Test Performed?

This test is ordered to:

Evaluate unexplained fatigue, weakness, pallor, or shortness of breath suggestive of anaemia

Classify types of anaemia (hypochromic, normochromic, or hyperchromic)

Investigate nutritional deficiencies, chronic diseases, or genetic blood disorders

Monitor response to treatments such as iron therapy or vitamin supplementation

Assess overall red blood cell health before surgery or during routine check-ups

Differentiate causes when combined with other indices like MCV and MCH

MCHC Normal Range

The MCHC normal range is typically 32–36 g/dL (or 320–360 g/L), though slight variations may occur depending on the laboratory method and reference population. Values are interpreted in context with the full CBC report.

MCHC Blood Test High

MCHC blood test high levels (above 36 g/dL) indicate denser haemoglobin packing in red blood cells, often termed hyperchromic. Possible causes include:

Hereditary spherocytosis

Autoimmune haemolytic anaemia

Severe burns

Liver disease

Sickle cell disease or haemoglobin C disease

Cold agglutinin disease

Artefacts from sample handling (e.g., haemolysis)

High values are uncommon and usually prompt further specialised testing.

MCHC Blood Test Low

MCHC blood test low levels (below 32 g/dL) suggest reduced haemoglobin concentration, typically hypochromic red cells. Common causes include:

Iron deficiency anaemia (most frequent)

Thalassaemia

Anaemia of chronic disease

Sideroblastic anaemia

Lead poisoning

Low results often correlate with microcytic anaemia and require evaluation of iron studies or other markers.

Preparation for the MCHC Test

No special preparation is usually necessary:

Fasting is not required.

Continue regular medications unless advised otherwise by your doctor.

Stay well-hydrated for easier venepuncture.

Wear loose sleeves for convenient arm access.

The Procedure

A qualified phlebotomist collects a small blood sample from a vein in your arm:

The site is cleaned with antiseptic.

A tourniquet is applied briefly.

Blood is drawn into a tube (part of CBC).

Gentle pressure and a bandage are applied post-draw.

The collection takes under a minute and is generally painless.

Understanding Results

Results are reviewed by a pathologist alongside other CBC parameters. Normal values indicate balanced haemoglobin concentration. Abnormal findings (high or low) are discussed with your doctor, who may recommend additional tests like serum ferritin, peripheral smear, or haemoglobin electrophoresis for definitive diagnosis.
