What is a Bone Marrow, Iron Stain Test?
The Bone Marrow, Iron Stain test is a specialised laboratory examination that uses a chemical dye called Prussian blue to detect iron in a bone marrow sample. A doctor may order this test when routine blood results suggest an iron disorder that needs closer investigation. It is also known as Perls' Stain or the Prussian Blue Stain for Iron. The sample is a small amount of liquid bone marrow drawn through a thin needle, usually from the hip bone.
What Does a Bone Marrow, Iron Stain Test Measure?
This test examines three key aspects of iron within the bone marrow. The findings help doctors understand how the body is storing and using iron at a cellular level.
| Component | What It Reveals |
|---|---|
| Iron stores (haemosiderin deposits) | The overall amount of iron held in bone marrow macrophages (immune cells that store iron) |
| Sideroblasts | Immature red blood cells that contain a normal number of iron granules (1 to 5), scattered in the cytoplasm |
| Ring sideroblasts | Abnormal cells where iron-loaded structures form a ring around the cell nucleus, indicating abnormal iron use |
Why is a Bone Marrow, Iron Stain Test Done?
This test is requested when a doctor suspects an iron-related blood disorder that cannot be fully assessed through routine blood tests alone. It provides direct information about iron stores and red blood cell development.
Common Symptoms That May Require This Test
Several symptoms may prompt a doctor to request a Bone Marrow, Iron Stain test. The following are the most common reasons for referral:
- Persistent fatigue that does not improve with rest
- Shortness of breath during everyday activity
- Pale skin, particularly noticeable on the inner eyelids or palms
- Rapid or irregular heartbeat
- Dizziness or lightheadedness
- Cold hands and feet
- Difficulty concentrating or mental fog
Conditions This Test Can Help Detect
The Bone Marrow, Iron Stain test procedure helps identify a range of blood and iron-related conditions:
- Iron deficiency anaemia, where the absence of stainable iron is considered diagnostic
- Haemochromatosis, a condition in which the body absorbs and stores excess iron
- Haemosiderosis, characterised by iron deposits in tissues, often linked to repeated blood transfusions
- Sideroblastic anaemia, a rare condition caused by abnormal iron use during red blood cell production
- Myelodysplastic syndromes (MDS), a group of blood cancers evaluated using iron staining to count ring sideroblasts
- Unexplained anaemia where inflammation and iron deficiency need to be distinguished
Bone Marrow, Iron Stain Test for Chronic Disease Monitoring
This test plays an important role in monitoring patients with myelodysplastic syndromes. It helps doctors assess ring sideroblast levels and iron status when determining the appropriate treatment plan. Patients receiving erythropoietin therapy also require baseline and periodic iron monitoring, and this test may be repeated at intervals to track how well the body is responding to treatment.
How to Prepare and What to Expect
Preparation for the Bone Marrow, Iron Stain test is straightforward, but it is essential to follow your doctor's specific instructions beforehand.
Do You Need to Fast?
No fasting is required for this test. You may eat and drink normally before your appointment. If sedation is planned, your doctor will give you separate pre-procedure instructions.
Practical Tips Before Your Test
A few simple steps will help ensure your appointment goes smoothly:
- Bring a detailed clinical history file, including your symptoms, previous test results, and family history, as this is required for the test
- Carry any recent laboratory reports to your appointment
- Inform your doctor about all medications and supplements you take, particularly blood thinners
- Arrange for someone to drive you home if sedation is used
- Wear loose, comfortable clothing that allows easy access to the hip area
Step-by-Step Procedure
The Bone Marrow, Iron Stain test procedure is carried out in a clinical setting by a trained specialist. Here is what to expect:
- You will be asked to lie on your abdomen or side, and the exam area will be cleaned and draped.
- The doctor will mark the collection site, which is usually the back of the hip bone (posterior iliac crest).
- A local anaesthetic is applied to numb the area and reduce discomfort. Sedation may also be offered.
- A small incision is made in the skin, and a hollow needle is inserted into the bone marrow cavity. A syringe draws out a small amount of liquid bone marrow (the aspirate).
- Pressure is applied to the site after collection, and a dressing is placed over the area.
- The aspirate is sent to the laboratory, where it is stained with Prussian blue dye and examined under a microscope by a specialist.
Factors That Can Affect Accuracy
Certain factors may affect how reliable or complete the results are:
- Aspirate smears without bone marrow fragments cannot be assessed for iron stores
- Smears with fewer than seven fragments may not give a complete picture
- Delay between collection and laboratory processing
- Quality of the staining technique and experience of the examining specialist
- Certain medical conditions, such as inflammatory states, can alter the appearance of sideroblasts
Understanding Your Bone Marrow, Iron Stain Test Results
Results from the Bone Marrow, Iron Stain test are assessed using Gale's grading scale for iron stores, alongside counts of sideroblasts and ring sideroblasts. Your doctor will review all findings together.
| Parameter | Normal Range | Notes |
|---|---|---|
| Iron stores (Gale's grade) | Grade 2 to 4 | Grade 0 to 1 indicates iron deficiency; Grade 5 to 6 indicates iron overload |
| Sideroblasts | 20% to 50% of erythroblasts | Normal cells have 1 to 5 iron granules scattered in the cytoplasm |
| Ring sideroblasts | Less than 15% of red blood cells present in bone marrow | 15% or more may indicate sideroblastic anaemia or myelodysplastic syndrome |
Gale's Grading Scale for Bone Marrow Iron Stores:
| Grade | Description |
|---|---|
| Grade 0 | No visible iron under high-power magnification |
| Grade 1 | Very slight; small iron particles just visible in a few cells under high-power magnification |
| Grade 2 | Slight; small, sparsely distributed iron particles visible under low-power magnification |
| Grade 3 | Moderate; numerous small iron particles throughout the marrow fragment |
| Grade 4 | Moderate heavy; larger iron particles with a tendency to clump together |
| Grade 5 | Heavy; dense, large clumps of iron throughout the fragment |
| Grade 6 | Very heavy; very large iron deposits, both inside and outside cells, obscuring cellular detail |
Disclaimer: These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain health states can alter how results appear:
In inflammatory conditions, the percentage of type 1 and 2 sideroblasts decreases, and macrophage iron remains normal or increases. This pattern differs from iron deficiency, where macrophage iron is reduced or absent. In young children, low or absent stainable iron stores are a normal finding and do not necessarily indicate iron deficiency.
How to Maintain Healthy Levels
These general tips support healthy iron balance as part of everyday wellness:
- Include iron-rich foods in your diet, such as lean meat, dark leafy vegetables, and legumes
- Pair plant-based iron sources with vitamin C to improve absorption
- Avoid taking iron supplements without medical guidance, as excess iron can be harmful to organs over time

Frequently Asked Questions
The Bone Marrow, Iron Stain test uses Prussian blue dye to examine bone marrow under a microscope. It is considered the gold standard method for assessing iron stores and helps diagnose iron deficiency anaemia, iron overload conditions, and sideroblastic anaemias.
The area is numbed with a local anaesthetic before the procedure, which reduces discomfort significantly. You may feel a brief pressure sensation when the sample is drawn. Sedation can be offered if you are anxious or if your doctor recommends it.
The bone marrow aspiration itself typically takes around 10 to 20 minutes. Additional time is needed for preparation and post-procedure care, particularly if sedation is used.
Ring sideroblasts are abnormal cells where iron-loaded structures form a ring around the cell nucleus. When they make up 15% or more of red blood cells in the bone marrow, this can indicate conditions such as sideroblastic anaemia or myelodysplastic syndrome. Your doctor will explain what this means for your specific situation.
No. Bone Marrow, Iron Stain test home collection is not available because collecting bone marrow requires a specialised medical procedure performed by a trained specialist in a clinical setting. You will need to visit a Lupin Diagnostics centre.
You should bring a detailed clinical history that includes your current symptoms, any previous test results, and your family history. Recent laboratory reports are also required. These help the specialist interpret your results accurately.
A routine serum ferritin or serum iron blood test measures iron levels circulating in the blood. The Bone Marrow, Iron Stain test directly examines how iron is stored and used within the bone marrow at a cellular level. It provides information that blood tests alone cannot offer, particularly in complex or unclear cases.
