What does Gettlers test detects ?

Ans. is 'b' i.e., Chloride content of blood in drowning Gettler test estimates chloride content of blood from both sides of hea. It is done for drowning. Normally the chloride content is equal in the right and left chambers of the hea (600 mg/100 m1). In fresh water drowning due to hemodilution the chloride content is decreased and in salt water drowning due to hemoconcentration the chloride content is increased in left side of hea. A 25% difference in chloride is significant but the test is of doubtful value.
