Some conditions can prevent blood from clotting properly, may cause the blood to clot too easily or cause clots to remain in the body for too long. Clotting (or coagulation) tests are often used to monitor patients taking anticoagulants - medications that decrease the ability of the blood to clot.
Anticoagulant medications are often prescribed to patients after they have suffered a heart attack or stroke. Those with arrhythmia (an irregular heart beat) may also take anticoagulants to prevent a first or recurrent stroke.
This test evaluates the clotting tendency of blood and the time it takes for clots to form using the standard measures of prothrombin time (PT), APTT and the International Normalised Ratio (INR) which is derived from PT. These tests can reveal if clotting factors are low or absent and can help to identify which ones. INR is typically used to help inform dosage for patients taking anticoagulants (commonly warfarin) and to monitor progress over time.
Fibrinogen is a protein that aids in the formation of blood clots. Low levels of fibrinogen are sometimes seen in cases of excessive clotting, such as disseminated intravascular coagulation (DIC).
Platelets (or clotting cells) are the smallest type of blood cell and are important in the blood clotting process. A raised platelet count may indicate an elevated risk of clots forming in the blood, while a low count may mean that you bruise easily or suffer from uncontrolled bleeding.

Haemoglobin carries oxygen and gives the red blood cell its red colour. This test measures the amount of haemoglobin in the blood and is a good measure of the blood's ability to carry oxygen around the body.
A high haemoglobin result can mean increased red cell production to compensate for chronically low oxygen levels in the blood caused by lung disease or living at altitude. While it can also indicate "blood doping" other causes can include dehydration, smoking and bone marrow disorders.
A low haemoglobin result indicates anaemia which can have many causes including pregnancy, blood loss, liver damage, iron deficiency and much more. A low haemoglobin level should be investigated in line with other symptoms and results.
HCT (haemocrit) measures the amount of space (volume) red blood cells take up in the blood.
Raised levels can result from pregnancy, living at altitude, dehydration as well as low availability of oxygen through chronic lung disease and even sleep apnoea.
Low levels indicate anaemia.
Red blood cell (RBC) count analyses the number of red cells in the blood. Red blood cells carry oxygen from the lungs to the rest of the body. They also carry carbon dioxide back to the lungs so that it can be exhaled.
A high count (thicker blood) means there is a chance that the red blood cells will clump together and block tiny blood vessels. This also makes it difficult for your red blood cells to carry oxygen.
A low count (anaemia) means that your body may not be getting the oxygen it needs and can be caused by nutritional deficiency (lack of iron, folic acid, vitamin B12), over-hydration as well as bleeding and bone marrow disorders.
MCV (mean corpuscular volume) reflects the size of your red blood cells.
A high result may indicate a vitamin deficiency of folate or vitamin B12 and is often seen in excessive alcohol consumption associated with liver inflammation.
A low result indicates anaemia, often caused by iron deficiency.
MCH (mean corpuscular haemoglobin) is the average amount of haemoglobin contained in your red blood cells.
Together with MCV and MCHC, MCH results can help in the diagnosis of different types of anaemia.
MCHC (mean corpuscular haemoglobin concentration) is the average concentration of haemoglobin in your red blood cells.
A high level can indicate the presence of spherocytes (a type of red bood cell with too much haemoglobin) or a deficiency of folic acid or vitamin B12 in the diet.
A low level can indicate chronic blood loss or iron deficiency.
RDW (red cell distribution width) shows whether the cells are all the same size or different sizes or shapes. Normally cells are fairly uniform, although a raised RDW result (indicating greater variaton in cell size and shape than is normally seen) can be caused by deficiency in iron, vitamin B12 or folic acid.
White blood cells are key to your body's immune or defence system. They fight infections and protect your body from foreign invaders such as harmful germs and bacteria.
A raised white blood cell (WBC) count can indicate recent infection, inflammation, trauma and even stress. Your WBC can also be raised when taking certain medications.
A decreased WBC can result from a vitamin deficiency such as folate or vitamin B12, as well as liver disease and diseases of the immune system.
Neutrophils are a type of white blood cell that are responsible for helping your body fight infection. When neutrophils are low you can be more vulnerable to illness and infection.
Neutrophils can be raised after severe stress on the body from a bacterial infection, recent exercise or sudden kidney failure.
Low neutrophils can be casued by a deficiency in vitamin B12 or folic acid, severe bacterial infection and some autoimmune diseases.
Lymphocytes are a type of white blood cell which fight bacterial and viral infections. They include T cells, B cells and natural killer cells.
Lymphocytes can be elevated for many reasons but it is common for them to be raised after recent infection, particularly after the flu. They can also be raised due to autoimmune disorders and some cancers.
The most common cause for lymphocytes to be depleted is the common cold.
Monocytes are a type of white blood cell that engulf and remove pathogens and dead or damaged cells from our blood. The heat and swelling of inflammation is caused by the activities of these cells.
Elevated monocytes can indicate chronic inflammatory disease, chronic infection, parasitic infection and Cushings disease.
Low levels can be due to autoimmune disorders such as lupus and rheumatoid arthiritis as well as drugs which affect the bone marrow such as those used in chemotherapy.
Eosinophils are a type of white blood cell whose function is to remove parasitic infections as well as to regulate inflammation to mark an infected site.
Levels of eosinophils can be elevated if the scale of inflammation is greater than necessary to control the damage (as is the case in asthma and allergic responses) as well as in parasitic and fungal infections, autoimmune diseases and skin disorders.
Low levels of eosinophils are not usually cause for concern and can be caused by the administration of steroids.
Basophils are a type of white blood cell that protect your body from bacteria and parasites such as ticks. They produce histamine and heparin and can respond incorrectly causing allergies, asthma and other inflammatory conditions.
An elevated basophil count can be due to inflammatory conditions such as Crohn's disease, ulcerative colitis and dermatitis, recent infection and hormone imbalance (e.g. hypothyroidism).
A low basophil count can be caused by pregnancy, stress and use of steroids.
A blood film report is an examination of the shape, size and number of blood cells under the microscope. Oxygen is carried less effectively by red blood cells if they are of abnormal size or shape, and this can result in anaemia. Too many or too few white blood cells can signify a blood disorder and can affect your body's ability to fight infection.
Platelets or clotting cells are the smallest type of blood cell and are important in blood clotting. When bleeding occurs, the platelets swell, clump together and form a sticky plug (a clot) which helps stop the bleeding.
If platelet levels are raised there is an increased risk of blood clots forming in blood vessels.
If platelet levels are too low there is a risk of easy bruising and uncontrolled bleeding.
MPV (mean platelet volume) is a measurement of the average size of your platelets. New platelets are larger than older ones and a raised MPV result occurs when increased numbers of platelets are being produced. MPV provides an indication of platelet production in your bone marrow.
