Hemoglobin (Hb)

Haemoglobin is the oxygen-carrying protein in red blood cells. A low concentration can identify anaemia and prompt an investigation of its cause.

Understanding the test

What does the Hemoglobin (Hb) test measure?

Also called Oxygen-Carrying Protein

A haemoglobin result can help investigate tiredness or breathlessness or follow a known anaemia. It measures how much oxygen-carrying protein the blood contains.

When it may be requested

Assessing anaemia

Haemoglobin reflects the blood's oxygen-carrying capacity and can help identify anaemia.

Following a response

Repeat values may help a clinician assess blood loss or a treatment response.

Before your sample

Prepare for collection

SpecimenWhole Blood (EDTA)
Your checklist0 of 2 ready

Fasting is unnecessary. Tell the team about recent bleeding, transfusion, iron treatment or pregnancy, especially when comparing haemoglobin over time.

The clinician takes blood from a vein into a tube that keeps it from clotting. The collection team sends the labelled specimen to the laboratory.

Reading your result

The result identifies a concentration, not the cause of a change. The blood count and clinical history help distinguish blood loss, nutrient deficiency and other possibilities.

What can affect it

  • Haemoglobin alone cannot identify iron deficiency or another specific cause.

Discuss the next step

Ask whether the red cell size, ferritin or other measurements point toward a particular explanation for a low haemoglobin.

Patient questions

Before you book

Does a low result prove I need iron?

No. Several conditions cause anaemia. Red cell measurements, iron studies and the clinical history can help identify which explanation fits.

Why is my haemoglobin high when I feel fine?

Dehydration can concentrate the blood and raise the measured haemoglobin. Smoking and living at high altitude can also raise it. If the result stays high, your clinician may compare earlier counts and look for other causes, even if you feel well.

What are the symptoms of low haemoglobin?

Low haemoglobin means less oxygen reaches the tissues, so the usual symptoms are tiredness, pale skin, dizziness and breathlessness on exertion. A slow fall can produce surprisingly few symptoms because the body adapts, so anaemia is often found on a routine test. Anaemia is a finding to investigate rather than a diagnosis, and your doctor looks for its cause.
