What is a Haemogram CBC Test?
The haemogram CBC test helps detect various disorders in the body like anaemia, blood cancers, infections, and other problems concerned with the immune system. The haemogram test cost is not very high and easily accessible with a CBC test near me option. Haemogram complete blood count test is a number of blood tests performed on a blood sample. The CBC test concentrates on the blood's three main components ie. White Blood cells, Red Blood Cells, and Platelets.
Which Tests are included in a Haemogram CBC Test?
The tests that are performed under a Haemogram CBC test are: Total white blood count: These are also the total number of white blood cell counts in the sample of the blood calculated in this haemogram test. This is used to determine the infections, allergic reactions, inflammation, or any other diseases that affect the WBC's as they are the most crucial part of the body's defence system. These blood cells are widely found in the lymphatic system and tissues. The different types of WBC's are: Neutrophils Lymphocytes Basophils Eosinophils Monocytes Total red blood count: These are also known as the erythrocytes, and produced in the marrow of the bone and released into the bloodstream once they mature. They have a lifespan of only 120 days, and hence they are continuously produced to replace the aged ones. This test calculates the number of RBC's in the blood sample, and they are used to find out iron, vitamin B12, and folate deficiencies. Haemoglobin: This CBC blood test measures the number of proteins that carry oxygen in the blood, and this is nothing but, again the RBC's and this test helps to identify whether the patient has a sufficient amount of such blood cells or is anaemic. Haematocrit: By doing this haemogram test, the total percentage of the blood volume of red blood cells is found out. This is another test to determine the condition called anaemia and is usually accompanied by the haemoglobin test. Mean cell volume: This complete blood count test is used to find out the different types of anaemia, which gives the average size of the red blood cells in a blood sample. This is also known as the mean corpuscular volume and is a compulsory part of the complete blood count test. Mean cell haemoglobin: Haemoglobin is the protein present in the red blood cells, and this CBC blood test measures the average quantity of haemoglobin present in a single red blood cell. Mean cell Haemoglobin concentration: This CBC blood test is similar to the mean cell haemoglobin test except that it measures the average concentration of haemoglobin in a single blood cell. Platelets count: This CBC test measures the number of platelets in the blood, and this haemogram test is used to diagnose thrombocytosis and thrombocytopenia. RBC distribution width-standard deviation: This is the standard deviation of the red cell volume divided by the mean cell volume. This complete haemogram test allows us to predict the mortality risk of the patient with its values. Neutrophils: As discussed earlier, this being a type of WBC and is used to determine how the chemotherapy is proceeding and other issues like bone marrow failure, aplastic anaemia, febrile neutropenia, congenital disorders like Kostmann syndrome and cyclic neutropenia, hepatitis A, B, C, HIV/AIDS, sepsis, leukaemia, rheumatoid arthritis, myelodysplastic syndrome, and certain other autoimmune diseases. Lymphocytes: This is another type of WBC test which helps to identify the conditions called influenza, lymphoma, Hodgkin disease, Wiskott-Aldrich syndrome, DiGeorge syndrome, inflammatory conditions or infections, and steroid usage. Monocytes: It measures this particular type of WBC, and this helps to monitor the health of the immune system and the blood. Eosinophils: This another CBC test used to measure this kind of WBC to diagnose the acute hypereosinophilic syndrome, asthma or hay fever, fungal infection, eczema, and Cushing's disease. Basophils: These are other types of WBC, and in this CBC haemogram, it is used to find whether the patient has diabetes, allergies, Crohn's disease, ulcerative colitis, lupus, or rheumatoid arthritis. Packed cell volume: This CBC test is to diagnose polycythemia and dehydration in an individual. It also estimates the need for other blood transfusions in a patient and helps monitor the response levels to other treatment procedures. Peripheral Smear Examination: This CBC test is done by viewing the blood sample under a microscope to count the various blood cells and check whether they look normal. This helps to look for the occurrence of parasites such as malaria and filaria. RBC distribution width-coefficient of variation: This CBC test measures the amount of red blood cell variation with regards to its volume and size. Platelet distribution width: This is done with a simple calculation using a formula. This always indicates whether there is a morphological change or inflammation that causes this to be activated. Mean platelet volume: This value is calculated with the help of the machine to find the average size of the platelets in the blood. This is used to diagnose problems like measles, hepatitis, and other virus invasions in the system. Platelet large cell ratio: The differential diagnosis of abnormal platelet count in the blood is the core cause to be done under this complete haemogram test. Platelet crit: This is a measure of the total platelet mass. Again, this is a more profound finding in a haemogram to diagnose cancers like lungs, gastrointestinal, ovarian, breast, or lymphoma. Absolute neutrophils count: This is the measure of the number of neutrophils in the blood. Absolute lymphocytes count: This is the measure of the number of lymphocytes in the blood. Absolute monocytes count: This is the measure of the number of monocytes in the blood. Absolute eosinophils count: This test helps to know the number of eosinophils in the bloodstream. Absolute basophils count: This test measures the number of basophils in the bloodstream. Erythrocyte sedimentation rate: In this, the rate of fall of erythrocytes in a blood sample inside a tube, and this test indirectly measures the degree of inflammation present in the human system.
When do I need to get a Haemogram CBC Test?
A complete haemogram test is done when the patient is experiencing problems like: It has an overall weak feeling throughout the day that does not get better with any remedy. Whole-body fatigue makes the individual challenging to perform daily routines with ease. An untold increase in temperature keeps frequently occurring with no response to medication. Bruises or bleeds without any external hurt, which either has clotting and other problems accompanied. If there is an inflammation or infection in the body, the healthcare provider will suggest that the patient take this test for further diagnosis. The spleen and the bone marrow malfunction or pose other complications.
How do I prepare for a Haemogram CBC Test?
A CBC haemogram is just a test done with the blood sample. So the prior preparation an individual should do before taking up this test is: The patient should stop taking medications that are diuretic, antibiotic and other steroids. An individual should refrain from smoking and vigorous exercise before appearing for this test, as it will alter the result. The patient does not need to fast or stop taking fluids or eating before a CBC blood test unless recommended by the doctors. An individual should be aware of the haemogram test cost and be prepared to face it.
