Question 15

What is a high red blood cell count?

Accepted Answer

A high red blood cell (RBC) count, also known as erythrocytosis or polycythaemia, means the number of red blood cells in the bloodstream is higher than normal. Red blood cells carry oxygen from the lungs to the rest of the body.

Question 21

What is low haemoglobin, and why is it a concern?

Accepted Answer

Low haemoglobin, also known as anaemia, is a condition where there is a reduced level of Haemoglobin in the blood. Haemoglobin is essential for transporting oxygen from the lungs to the rest of the body. Low levels can lead to symptoms such as fatigue, weakness, and shortness of breath, impacting overall health and quality of life.

Question 22

When would an RDW blood test be needed?

Accepted Answer

RDW blood tests may be requested when a healthcare provider suspects or wants to monitor certain medical conditions. It can help diagnose and manage anaemia, as different types of anaemia can cause variations in red blood cell size.

Question 23

How much lymphocyte count can be alarming?

Accepted Answer

More than 40% of lymphocytes are high, but when the count goes above 70%, it becomes alarming, and you should seek professional advice.

Question 27

Can thalassemia be cured?

Accepted Answer

The sole treatment for thalassemia is a bone marrow or stem cell transplant; however, due to the high dangers involved, these procedures are performed infrequently. Bone marrow, the spongy substance located in the centre of some bones, is where stem cells are created. These cells can differentiate into several blood cell types.

Common symptoms of iron deficiency include fatigue, weakness, pale skin, shortness of breath, dizziness, headaches, brittle nails, and an unusual craving for non-food items such as ice or dirt (known as pica).

Question 30

What are the symptoms of a high white blood cell count?

Accepted Answer

Symptoms can vary based on the underlying cause. Common signs may include fever, fatigue, weakness, unexplained weight loss, joint pain, and frequent infections.

Question 31

What causes myelodysplastic syndromes?

Accepted Answer

The exact cause of MDS is often unknown. Still, it can be linked to factors such as genetic mutations, exposure to certain chemicals or radiation, and sometimes, as a result of previous cancer treatments such as chemotherapy or radiation therapy.

ThalassemThalassemiathe body causes reduced production of healthy haemoglobin, leading to anaemia and potential complications such as fatigue, jaundice, and organ damage.

Question 35

How is a high red blood cell count diagnosed?

Accepted Answer

Diagnosis typically involves a complete blood count (CBC) test, which measures the number of red blood cells in the blood. Additional tests may be conducted to determine the underlying cause, such as measuring oxygen levels, testing for erythropoietin levels, or genetic testing.

Question 36

What are the symptoms of a high haemoglobin count?

Accepted Answer

Symptoms may include fatigue, dizziness, headaches, high blood pressure, blurred vision, and an enlarged spleen. However, some individuals may not experience noticeable symptoms and only discover the condition through routine blood tests.

Question 37

What are the stages of haemostasis?

Accepted Answer

Haemostasis occurs in three main stages:

Vascular Spasm: Immediate constriction of the blood vessel to reduce blood flow.
Platelet Plug Formation: Platelets adhere to the site of injury and aggregate to form a temporary "platelet plug."
Coagulation: A series of enzymatic reactions involving clotting factors that result in the formation of a stable fibrin clot.

Question 38

What conditions can cause petechiae?

Accepted Answer

Petechiae can be caused by conditions like thrombocytopenia, infections, vasculitis, and certain medications that affect blood clotting.

Question 39

What are the common causes of purpura?

Accepted Answer

Common causes include blood clotting disorders, vasculitis, and medications like blood thinners.

Question 40

How soon can I return to work after a stem cell transplant?

Accepted Answer

Getting time to recover completely is more important, as the immune system is weakened, and the body is more susceptible to attacks than ever. It is advised to return to work 3-6 months after an autologous stem cell transplant, and the period is 6-12 months for an allogeneic process. However, it is recommended to consult a medical practitioner before considering returning to work.

Question 41

Accepted Answer

Their main function is to identify and destroy harmful pathogens and produce antibodies to prevent infections.

Question 43

What causes low RDW?

Accepted Answer

Low RDW (Red Cell Distribution Width) may be caused by conditions that result in a narrow range of red blood cell sizes. This can occur in conditions such as iron deficiency anaemia, thalassemia, or chronic diseases with stable red blood cell populations.

Question 44

How many types of lymphocytes are there?

Accepted Answer

There are many subdivisions of lymphocytes, but they can be categorised into 5 main types: Helper T-cells, Regulatory T-cells, Cytotoxic T-cells, Memory T-cells, and Natural Killer cells.

Accepted Answer

People at higher risk for iron deficiency include pregnant individuals, infants and young children, menstruating women, vegetarians or vegans (who may have a lower dietary intake of iron), and individuals with certain gastrointestinal conditions that affect iron absorption.

Question 48

How do you diagnose thalassemia?

Accepted Answer

Accepted Answer

Thalassemia is broadly categorised into two main types: alpha thalassemia and beta thalassemia.

Question 55

Is a high red blood cell count always a cause for concern?

Diagnosis typically involves a complete blood count (CBC) test to measure haemoglobin levels. Additional tests, such as arterial blood gas analysis, erythropoietin levels, and imaging studies, may be conducted to determine the underlying cause.

Question 57

What factors affect haemostasis?

Accepted Answer

Haemostasis can be affected by several factors, including the health and integrity of blood vessels, the number and functionality of platelets, the presence of clotting factors, and the balance between pro-coagulant and anti-coagulant mechanisms in the body.

Question 58

Are petechiae serious?

Accepted Answer

Petechiae can be a symptom of serious underlying conditions, and a healthcare provider should evaluate it to determine the cause.

Question 59

Question 60

What are the most common stem cell transplants?

Accepted Answer

The most common ones are:

Autologous stem cell transplant
Allogeneic stem cell transplant
Cord transplant
Reduced-intensity transplants

Question 61

What are the symptoms of low haemoglobin?

Accepted Answer

Symptoms of low haemoglobin can vary but often include fatigue, pale skin, shortness of breath, dizziness, cold hands and feet, chest pain, headaches, and irregular heartbeat. These symptoms occur because the body is not receiving enough oxygen.

Question 62

Why is RDW high in iron deficiency anaemia?

Accepted Answer

In iron deficiency anaemia, the body lacks sufficient iron to produce haemoglobin, leading to smaller and larger red blood cells. This variation increases RDW (Red Cell Distribution Width) levels, indicating the range of cell sizes.

Question 63

What are killer T-cells?

Accepted Answer

Killer T-cells destroy other cells they deem targets by directly attacking them as they possess special molecular weapons. They are also known as cytolytic or cytotoxic.

Question 64

How do I increase the range of my monocyte count?

Accepted Answer

There are treatments you can opt for to raise the monocyte count. You need to talk to your healthcare provider, get medicines for underlying conditions (if any), boost the immune system with essential vitamins, and treat present infections in the body.
