When a low haemoglobin needs a blood specialist | CION Cancer Clinics
Most people with low haemoglobin can be treated by their family doctor or physician. You should ask for a haematologist when the cause is still unclear after first tests, when iron or vitamins have not raised the count, or when white cells or platelets are abnormal too. This page lists the signs that call for a referral, the ones that need emergency care today, and what the first appointment involves. At CION Cancer Clinics, our haematologist cares for anaemia, bleeding, clotting and inherited blood disorders, with ArogyaSri, CGHS and cashless insurance accepted.

The short answer
Do you need a haematologist for low haemoglobin?
Most people with low haemoglobin do not. A family doctor or physician can find and treat the common causes. You need a haematologist, a blood specialist, when the cause stays unclear, treatment is not working, or other parts of the blood count are abnormal too.
Why most low counts start with your own doctor
The usual reasons are lack of iron, heavy periods, low vitamin B12 or folate, worms, and long-term illness such as kidney disease. These are found with routine blood tests and a few questions. A physician manages them well, and going straight to a specialist often adds cost and waiting without changing the plan.
What a haematologist adds
A haematologist looks at the whole blood picture at once. They read the blood under a microscope, look for inherited conditions such as thalassaemia, and decide whether the bone marrow, where blood is made, needs to be examined. Their job is to find the cause when the simple explanations have not fitted.
Who is often reading this
Often it is a son or daughter holding a parent's report, trying to work out whether a referral is needed. The sections below give you the signs to look for, and the questions to take to the doctor who ordered the test.
Normal ranges differ between laboratories. One result is read alongside symptoms and a repeat test, never on its own.

When it is not a referral but an emergency
Breathlessness at rest, chest pain, fainting, black stools, vomiting blood, or yellow eyes with very dark urine need care today. So do a high fever with unexplained bruising or bleeding gums. Go to the nearest emergency department or call 108. Do not wait for a specialist appointment, and take every blood report you have with you.

Which situations mean you should ask for a haematologist?
One of these on its own is a reason to ask your doctor about a referral. It is not a reason to panic.
More than one count is abnormal
Low haemoglobin together with low or very high white cells or platelets points to a problem where blood is made. This needs a specialist opinion, not only iron or vitamin tablets.
Treatment has not worked
You have taken iron or vitamins as prescribed and the count has not risen, or it rose and fell back again.
Worth mentioning
- How long you took the tablets
- Any missed doses or stomach upset
The cause is still unknown
Iron, B12, folate, kidney and thyroid tests have come back and none of them explains the low count.
Red cells are being destroyed
Yellow eyes, dark urine and a raised bilirubin or LDH on the report can mean red cells are breaking down early. This is called haemolysis.
Something runs in the family
A relative has thalassaemia, sickle cell disease or G6PD deficiency, or a couple is planning a pregnancy and one partner has small red cells.
Other signs come with it
Swollen glands, drenching night sweats, weight loss you cannot explain, bone pain or a swollen belly alongside a low count.

What to expect
What happens at a first haematology appointment?
-
Your story and your reports
The haematologist asks about tiredness, bleeding, diet, periods, medicines and family history. Old reports matter as much as new ones, because the trend over months often shows more than one result.
-
An examination
They check for paleness, yellow eyes, swollen glands, and whether the spleen or liver is enlarged. These signs point towards some causes and away from others.
-
Targeted blood tests
Often a blood smear, a young red cell count, iron studies, and tests for inherited haemoglobin types. Your doctor explains why each one is being asked for.
-
A bone marrow test, only if needed
Most people never need one. If the blood tests point to the marrow, the team explains why, what it involves and where it will be done.
-
A plan, explained to you
At CION, complex cases are discussed by a tumour board, a group of specialists reviewing together, and care is coordinated with qualified centres where a test or treatment is done elsewhere.
Commonly believed
What do families fear about being sent to a haematologist?
"Being sent to a blood specialist means it is cancer."
Most people referred for a low haemoglobin turn out to have a non-cancer cause, such as thalassaemia trait, poor iron absorption or long-term illness. A referral means the answer needs a closer look. It is not a diagnosis.
"We can just keep taking tonics until it improves."
Tonics and repeated iron courses can hide a problem while the real cause goes unchecked. If the count has not risen, more of the same is rarely the answer. Ask what else should be tested.
"A blood transfusion will fix it for good."
A transfusion raises the count for a while. It does not treat the reason the count was low. Without finding that reason, the count usually falls again.
"Every haematologist visit ends in a bone marrow test."
Most questions are answered with blood tests alone. A marrow test is suggested only when blood results point to the marrow, and the reason is explained to you first.
Before you go
What should you bring, and what can this page not tell you?
Bring every blood report you have, in date order, with the names of all medicines and supplements. Write down when the tiredness or other symptoms began. A clear timeline saves repeat tests and shortens the first visit.
Questions worth asking
Ask what the most likely cause is, and what else is still being ruled out. Ask which test will settle it, and when you should expect results. Ask what change in symptoms should bring you back sooner. If a bone marrow test is suggested, ask why, and where it will be done.
What this page cannot tell you
It cannot tell you whether your own report needs a specialist. That depends on your symptoms, your age, your history and how the numbers have changed over time. It also cannot rule anything in or out. If you are unsure, ask the doctor who ordered the test whether a referral makes sense.

Common questions about seeing a haematologist
Do I need a referral letter to see a haematologist?
Not always. Many private clinics, including CION, see people directly. A note from your family doctor still helps, because it explains what has been tried and why they are concerned. Under some schemes and insurance plans a referral is required, so check your current rules before booking.
Is a haematologist the same as an oncologist?
No. A haematologist treats all blood conditions, from low iron and thalassaemia to clotting problems and blood cancers. An oncologist treats cancers in general. Most people who see a haematologist for low haemoglobin do not have cancer, so the visit itself should not be read as bad news.
How low does haemoglobin have to be for a referral?
There is no single cut-off. A mildly low count with abnormal platelets can matter more than a lower count with a clear cause. Doctors look at how fast it is falling, other counts, symptoms and age. Ranges also differ between laboratories, so ask your doctor to read your number in context.
My father is elderly. Is a low count just age?
Low haemoglobin is common in older people, but it is not simply part of ageing. It often has a cause worth finding, such as kidney disease, slow bleeding from the gut, low B12 or a marrow problem. Ask his doctor whether it has been explained before accepting it as normal for his age.
Should I stop iron tablets before the appointment?
Do not stop or change any medicine on your own. Some tests are affected by recent iron or vitamins, so tell the clinic what you are taking when you book. The haematologist or your own doctor will say whether anything should change before the tests.
Can a haematologist look at reports online first?
Often, yes. Sharing reports lets the team judge whether an in-person visit is needed and which tests to arrange. It is useful for families in Telangana and Andhra Pradesh districts who would travel to Hyderabad. It cannot replace an examination when one is needed.
What if my child has low haemoglobin?
Iron shortage and worms are common in children, and a paediatrician usually treats these first. Ask about a haematologist if the count does not respond, if other counts are abnormal, if there is a family history of thalassaemia or sickle cell disease, or if your child has yellow eyes, bruising or repeated fevers.
Are haematology tests covered by schemes or insurance?
It depends on the scheme and the reason for the tests. Aarogyasri, PM-JAY, CGHS, ECHS, EHS and cashless insurance are accepted at CION for eligible care. Entitlements change, so call the helpline with your card details and we will check your current cover before you travel.
