Sample type: BLOOD, WHOLE BLOOD-EDTA
Age group: All age group
The hemoglobin. total and differential leucocyte count test are done as a part of a complete blood count. It is done in case of signs and symptoms of anemia, polycythemia, leukemia, or leukopenia. It is done at regular intervals to monitor the ongoing response to the treatment. The platelet count helps to determine the number of platelets in the blood. It helps to screen, diagnose, or monitor the conditions that affect the number of platelets. ESR is done to evaluate the degree of inflammation present in the body.
The hemoglobin, total, leucocyte count, differential leucoucyte count and ESR test is done:
• As a part of routine health check-up
• As a part of complete blood count
• To evaluate the hemoglobin content in the blood
• To monitor the overall health of an individual such as weakness, fatigue, fever
• In cases when there are signs and symptoms related to conditions/diseases related to blood cells such as weakness, fever, inflammation, or bleeding.

Frequently asked questions
How is the blood sample taken?
To take the blood sample, a tourniquet (elastic) band is placed tightly on the upper arm. The patient is asked to form a fist. This helps in the buildup of blood filling the veins and it becomes easy to collect the blood. The skin is cleaned before inserting the needle in the vein in order to prevent bacteria from entering. After cleaning, the needle is inserted into the vein in the arm and the blood sample is collected in the vacutainer.
What factors can affect hemoglobins level?
The factors which can affect hemoglobins level include recent blood transfusion and pregnancy.
What additional tests can be advised along with the hemoglobin, TLC, DLC and ESR test?
The additional tests which can be advised along with hemoglobin test depend upon the cause which needs to be diagnosed. The other tests include blood smear, iron studies, reticulocyte count, vitamin B12 and folate levels, and bone marrow examination.
Which individuals are at risk of low hemoglobin levels?
The individuals which are at risk of low hemoglobin levels include women of childbearing age, nutritional deficiencies, people who underwent surgery, people who have been severely injured, kidney disease, cancer, HIV/AIDS, inflammatory bowel disease, chronic infection, or chronic inflammatory disorders.
What are the signs of abnormally low hemoglobin levels?
The signs of abnormally low hemoglobin levels include fatigue, pale skin, fainting, and shortness of breath.
What is the normal function of platelets?
The platelets play an important role in normal blood clotting.
How do platelets help to clot blood?
The other tests that can be advised along with platelet tests include CRP test, ESR test, test for infectious diseases such as tuberculosis, Prothrombin time, Iron studies, etc.
What other tests can be advised along with the platelets test?
Whenever there is any injury, the platelets adhere to the injury site, aggregate together with the platelets, and release chemicals that help in causing aggregation of other platelets.
What are giant platelets?
Giant platelets term is used for those platelets which are abnormally large. They might be seen in disorders like immune thrombocytopenic purpura and in rare inherited disorders such as Bernard-Soulier disease.
