What is MCH in Blood Test: Normal Range, Procedure, Preparation, & More

Posted by

Blood tests are essential in diagnosing various health conditions. One such test is the MCH blood test, which helps measure the average amount of hemoglobin in red blood cells. Understanding the MCH blood test meaning is crucial in detecting anemia and other blood disorders. This blog provides a detailed overview of the MCH blood test definition, its normal range, procedure, preparation, and implications of MCH blood test low or MCH blood test high levels.What is MCH Test

What is MCH Blood Test?

The MCH blood test (Mean Corpuscular Hemoglobin test) measures the average amount of hemoglobin per red blood cell. Hemoglobin is a protein in red blood cells responsible for oxygen transport. A MCV and MCH blood test is often conducted together to assess overall blood health.

The MCH blood test definition states that this test helps in diagnosing anemia and other blood-related disorders. It is part of a standard Complete Blood Count (CBC) test.

MCH Blood Test Meaning & Importance

The MCH blood test meaning revolves around measuring hemoglobin levels to assess red blood cell function. It is a crucial parameter that helps detect conditions like iron deficiency anemia, vitamin B12 deficiency, and macrocytic anemia. Along with MCV and MCH blood test, doctors can determine the size and hemoglobin content of red blood cells.

Normal Range for MCH Blood Test

The normal range for MCH blood test varies slightly among laboratories. However, the general reference range is:

  • Normal Range: 27 – 33 picograms (pg) per cell
  • MCH Blood Test Low: Below 27 pg per cell
  • MCH Blood Test High: Above 33 pg per cell

These values help determine whether a person has anemia or other blood disorders.

Procedure of MCH Blood Test

The MCH blood test is a simple procedure conducted as part of a CBC test.

Step-by-Step Process:

  1. A healthcare provider cleans the skin and inserts a needle into a vein.
  2. A small blood sample is drawn into a test tube.
  3. The sample is sent to a laboratory for analysis.
  4. Results are usually available within 24-48 hours.

Preparation for MCH Blood Test

No special preparation is needed for the MCH blood test. However, some recommendations include:

  • Fasting: Not required unless specified by the doctor.
  • Medication: Inform your doctor about any ongoing medications.
  • Hydration: Drink plenty of water before the test.

MCH Blood Test Low: Causes & Symptoms

A MCH blood test low result indicates low hemoglobin levels in red blood cells. This condition is often linked to anemia.

Causes of Low MCH Levels:

  • Iron Deficiency Anemia
  • Chronic Diseases
  • Thalassemia
  • Blood Loss

Symptoms of Low MCH:

  • Fatigue
  • Weakness
  • Shortness of breath
  • Dizziness

MCH Blood Test High: Causes & Symptoms

A MCH blood test high result means there is excess hemoglobin per red blood cell. This may indicate macrocytic anemia.

Causes of High MCH Levels:

  • Vitamin B12 Deficiency
  • Folate Deficiency
  • Liver Disease
  • Thyroid Disorders

Symptoms of High MCH:

  • Pale skin
  • Weakness
  • Numbness in hands or feet
  • Confusion or memory issues

MCV and MCH Blood Test: What’s the Connection?

The MCV and MCH blood test are often performed together. MCV (Mean Corpuscular Volume) measures the size of red blood cells, while MCH measures the hemoglobin content. These tests help doctors diagnose different types of anemia:

  • Low MCV & Low MCH: Microcytic anemia (Iron deficiency)
  • High MCV & High MCH: Macrocytic anemia (Vitamin B12 deficiency)
  • Normal MCV & Low MCH: Normocytic anemia (Chronic disease anemia)

7 Natural Approaches to Increase MCH Levels

If you have low MCH levels, these natural methods may help boost them:

  1. Increase Iron Intake: Consume iron-rich foods like spinach, red meat, and lentils.
  2. Boost Vitamin B12: Include eggs, dairy, and fish in your diet to prevent vitamin B12 deficiency.
  3. Consume Folate-Rich Foods: Leafy greens, nuts, and beans help increase folate levels.
  4. Stay Hydrated: Drinking enough water improves overall blood health.
  5. Limit Processed Foods: Reduce intake of processed and junk food that may interfere with nutrient absorption.
  6. Regular Exercise: Physical activity improves blood circulation and oxygen transport.
  7. Reduce Alcohol Consumption: Excessive alcohol can impact red blood cell production negatively.

Implementing these lifestyle changes can naturally improve MCH blood test low results.

When to See a Doctor?

If you experience symptoms like chronic fatigue, dizziness, or shortness of breath, consult a doctor. They may recommend an MCH blood test and other related tests to identify underlying health conditions.
