HEMOGLOBIN

 

HEMOGLOBIN ( Hb )

Hemoglobin is the most important component of red blood cells. It is composed of a protein called haem, which binds for carbon dioxide . Abnormilities of an individual’s hemoglobin value can indicate defects in the normal balance between red blood cell production and destruction. Both low and high values can indicate disease states.

Hemoglobin is a protein in red lood cells that carries oxygen from the lungs to the human body’s  tissues  & organs,it also carries carbon dioxide back to the lungs.

Hemoglobin is a most important  component of RBC(red blood cells) and gives them their colour.

How is hemoglobin measured

·         A hemoglobin test  measures the amount of hemoglobin in your blood.

·         This test is usully part of a complet blood count(CBC)

·         The amount of hemoglobin in whole blood is expressed in grams per deciliter(g/dl)

Normal range of hemoglobin

·         Males                   :               14 to 18 g/dl (138-172 gram per liter(g/L )

·         Female                :               12 to 16 g/dl  ( 121 – 151 gram per liter (g/L )

·         Child                     :               newborn             :-  14 to 24 g/dL      ( 140 – 240 gram per liter (  g/L )

Infant                    :-    9.5 to 13.0 g/dL ( 95 – 130 gram per liter(g/L )

Cause of low hemoglobin

·         A diet that is too low in iron, folate, & vitamin B12

·         Significant bleeding

·         Pregnancy

·         Genetic conditions such as sickle cell anemia & Thalassemia.

·         Cancer leukemia & Lymphoma

Symptoms of low hemoglobin

·         Weakness

·         Headaches

·         Bleeding

·         Chest pain

·         Irregular heartbeat

·         Cold hand and feet

·         Fatigue

·         Dizziness

·         Paaler then usual skin

·         Shortness of breath

Increasing Hemoglobin

Affect of hemoglobin

Altitude,Diet,Activity , Certain medicines, Dehydration , Smoking , & genetic Conditions.

WHY THE TEST IS PERFORMED

The hemoglobin test is a common test and is also always done as part of a CBC. Reasons or conditions for ordering the HB% test include:-

·         Before & after major surgery

·         Blood in your stools, or vomiting.

·         Chronic medical problems, such as kidney disease or certain types of arthritis

·         During pregnancy

·         Fatigue, poor health, or unexplained weight loss

·         Headaches

·         Heavy flow menstrual problems

·         Leukemia & other bone marrow related problems

·         Monitoring during cancer treatment

·         Poor nutrition

 

Risks

There is little risk involved with having your blood taken. Veins & arteries vary in size from one persons to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight, but may include:-

·         Excessive bleeding

·         Fainting or feeling lightheaded

·         Multiple punctures to locate veins

·         Hematoma  (blood buildup under the skin )

·         Infection ( a slight risk any time the skin is broken )

Rericulocyte Staining process

  Rericulocyte Staining process A reticulocyte stain is a technique a day of Highlight RNA in reticulocytes, A type oc Immuture RBC. This stain commonly use in Hematology department in pathology lab. Edta sample mixed with Reticulocyte staining Solution(Methylene blue) ↓ After Mixed incubate at room temperature. ↓ Prepare   a blood smears ↓ Wait A slide Air-dried the smear ↓ Examined under microscope ↓ The number of reticulocyte count in the patient blood sample is countyed and expressed a percentage   The stain show the RNA in reticulocytes as a blue colour against the pink colour of the rest of the cell. The pattern of the blue colour indicatye the stage of the reticulocyte A hight reticulocyte count can indicate that immutur red blood cells are not surviving longenough, & that the bone marrow needs to increase production. The reticulocyte count is an important role of monitoring of red blood cellssurvival & formation activity o...

MICROSCOPE

                                     MICROSCOPE Introduction of microscope The microscope is indispensable for a clinical laboratory technician. It is very important to have a sound knowledge of the microscope which is going to be a constant comparing in his daily work. To obtain desired magnification for visualizing the objects, the scientists did untiring efforts. The world microscope is derived from two Greek words - ''micro'' (small) and ''scope'' (view). Simple microscope discoveries by Anthony von Leeuwenhoek (1632-1723) and subsequently compound microscope by Robert Hook (1635-1703) were made. It is an instrument by which very small things can be seen which are not seen by the necked eye. This is done by producing an enlarged and well defined image of the objects by a system of lens. Principle of microscope The light beam, which falls on the object, p...
