Achard Test
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
The Achard test is a renal function test using the intramuscular injection of methylene blue. In the 1930s, its diagnostic value decreased because methylene blue can form leuko-bases that obscure test results.
Encyclopedia entry (1928–1936)
ACHARD TEST (Achard), an investigation of kidney function using the intramuscular injection of methylene blue. With normal renal permeability, the blue dye is excreted in the urine after 30 minutes. A delay in excretion indicates a reduced permeability of the kidneys. At the present time, the value of the Achard test has decreased because the dye can form leuko-bases, which obscure the diagnosis. (For details, see Nephrosis and Nephritis—functional investigation.)
