A

BARBERIO’S TEST

89
Q

A

ACID PHOSPHATASE TEST

90
Q

PROCEDURE:

A

ALTERNATIVE ACID – PHOSPHATASE TEST

90
Q

ACID PHOSPHATASE TEST POSITIVE RESULTS:

A

PURPLE COLOR

90
Q

A

ACID PHOSPHATASE TEST

90
Q

ACID PHOSPHATASE TEST REAGENT/CHEMICAL:

90
Q

is the enzymes present in semen.

A

PHOSPHATASE

90
Q

Alphanaphtol by the acid phosphatase combines with the diazonium salt to form the color. The reaction takes place for 30 seconds on fresh stains.

A

ALTERNATIVE ACID – PHOSPHATASE TEST

90
Q

PROCEDURE:
a. Moisten with water a piece of filter paper.
b. Swab the stained area with the filter paper.
c. The acid phosphatase will be transferred to the filter paper.
d. Add a drop or two Alpha naphthyl phosphoric acid and Brentamine fast blue B.

ACID PHOSPHATASE TEST

90
Q

ALTERNATIVE ACID – PHOSPHATASE TEST
REAGENT/CHEMICAL:

A

92
Q

-The identification of spermatozoa is at present the only specific test for semen.

A

THE MICROSCOPIC EXAMINATION OF SEMEN AND SEMINAL STAINS
