Raygat's test is used for ?
Ans. is 'b' i.e., Specific gravity of lung Hydrostatic test (Raygat's test, 1" life test) : The specific gravity of a non-respired lung is 1040-1050 and of a respired lung is 940-950, so, after respiration lung floats on water (specific gravity of water is 1000). False positive hydrostatic test may occur (i.e.non-respired lung may float) in decomposition and in attempted aificial respiration. False negative hydrostatic test (i.e. respired lung may sink down) may occur in atelectasis, pulmonary oedema, bronchopneumonia, and congenital syphylis.
