PRINCIPLE INVOLVED IN THE FOUR PRELIMINARY COLOR TEST FOR BLOOD
The peroxidase present in hemoglobin acts as career of oxygen from the hydrogen peroxide to the active ingredients of the reagents (benzidine, guaiac, phenolphthalein and leucomalachite) and produces the characteristic colored compounds by oxidation.
Peroxidase-is an enzyme that accelerates the oxidation of several classes of organic compounds by peroxide.
THE CONFIRMATORY TEST FOR BLOOD
The actual proof that a stain is blood consists of establishing the presence of the characteristic of blood pigment hemoglobin or one of its derivatives. Hemoglobin is the red coloring matter of the red blood cells of the blood.
THE THREE CONFIRMATORY FOR BLOOD
The three confirmatory tests for blood that determine whether stain is really blood are:
1. Microscopic Test
2. Microchemical Test or Microcrystalline Test
3. Spectroscopic Test
A. THE MICROSCOPIC TEST FOR BLOOD
Microscopic test is useful for the demonstration and mensuration of blood corpuscles for making the distinction between mammalian, avian, piscine and reptilian blood for the investigation of menstrual, lochial and nasal charges. In short it differentiates mammalian, avian, piscine and reptilian blood.
Method of Microscopic Examination:
1. Take two small fragments of the dried blood.
2. Place each fragment on separate slides with a drop of 0.9% salt solution.
3. The slides are put in a covered dish to prevent evaporation and the preparation allowed to stand for 1-2 hours.
4.One of the slides is examined as wet preparation.
5. The other preparation is spread evenly over the slide, allowed to dry and stained by:
