Narayan Reddy 31st ed. 405Tests for Detection ofSeminal Stain Mnemonic- Creat Acid Fast Bacilli Acid phosphatase test: to detect Aspermia cases BarberioS test: to detect Spermine yellow needle shaped spermine picrate Creatine phosphokinase test: for old seminal stain Florence test: choline crystals of semen shows fluoroscence when examined Rhombotic crystals of choline iodide Most specific test for seminal stain: Isoenzyme LDH assay For dry seminal stain: UV rays used Blood Benzidine test Best preliminary test as it detects blood present in dilution of 1 in 3 lakhs. Color produced: Deep Blue Not used because it is a potential carcinogen.Kastle-MayerPhenolpthalein test- color produced is Pink Purple.Microchemical test: based on RBC content of blood.1. Takayamas test: Hb converted to Haemochromogen crystal. Salmon pink feathery haemochromogen crystals are obtained.2. Teichmanns Haemin crystal test: Hb converted into HeminHematin crystals. Brown rhombic haemic crystal are seen3. Spectroscopic test: Most specificconfirmatory method for blood stain test4. Thin layer chromatography TLC5. ElectrophoresisNOTE: Test to distinguish human vs. animal blood- Precipitin Test,
