                             XI.            Hepatitis-C,D &E virus.

 

Ø  Laboratory diagnosis of Hepatitis ‘B’ virus:

                                  I.             Demostration of virus by using immune electron microscope from fecal specimen.

                                 II.            CIE ( Counter in immune electrophoresis ).

                               III.            RIA & ELISA technique are done:-

                              IV.            The following serological and viral marker are done.

a.       Detection of HBSAg – Appears early in blod vafter 6 weeks.

b.       Demonstration of Anti –HBS – Appears after 3 months against HBSAg in serum.

c.       Detection of HBEAg – Derived core protein.

d.       Anti HBe – Appears after disappearencer of HBeAg.

e.       Anti HBc – Detection in serum of Acute hepatitis-B.

f.        HBV DNA – Detected by southeron blot technique present in acute stage.

                                V.            Isolation of virus on tissue culture.

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...

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...
