Type of Test	Description
Positive Test	Test given a positive results; indicating the presence of the expected substances
False Positive Test	Test given a positive result despite the no presence of the expected substances
Negative Test	Test given a negative result; indicating no presence of the expected substances.
False Negative Test	Test gave a negative result despite the presence of expected substances.

Benzidine	Upon the presence of blood, the benzene solution reacts to form a dark blue color.
Guaiac	Used to look for invisible blood occults in a sample; yield a blue color for a positive result.
TMB	Modified form of benzidine test to remove its negative effects; it yield a blue-green color for a positive result
Hemastix	A strip test that can be used to detect blood by mixing the sample with distilled water; green indication of positive result
Ring Precipitin	Mix liquid of antiserum from animals with a blood sample. If a white line is formed between the two fluid rings then, it is a positive result
Ouchterlony Double Diffusion	Similar to ring test expect the antiserum is put in a central well wti surrounding wells; a barrier is formed
Phenolphthalein	Use a swab to mix the phenolphthalein to sa sample; pink appearance shows the presence of blood
Lattes Crust	Blood is added to a stain where it would react with the antibodies in the blood sample to determine its type
Luminescence	Utilizing fluorescence and alternate light source to illuminate blood presence; green glow
Chemiluminescence	Utilizing luminol solution and chemical reaction to illuminate blood presence; blue white glow
Teichmann	Use glacial acetic acid to mix with the sample and heat up; [positive result is when reddish brown and rhomboid-shaped crystals are formed
Takayama	Use pyridine solution to mix with samples; positive results when solution color changed to purple to pink
