Use of crude DNA to detect HVT in field samples by HVT LAMP-LFD assay. Crude DNA prepared from 20 mg sample material (organs, tumors, feather tips, or poultry house dust) by direct heating was successfully used for detection of HVT by the HVT LAMP-LFD assay. A band at the test line (T) shows a positive result. A band at the control line (C) shows a negative result.
