    4.0 4.1 4.1.1 immunology and Serology (See also 2.6.3) Serological investigations require blood taken into a dry sterile container (Code White) and allowed to clot. The specimen should reach the laboratory the same day or after overnight refrigeration at 4°C. For postal transmission it is preferable that the serum first be separated from the clot with sterile precautions. Laboratory Investigations for the Diagnosis of Syphilis Suspected Early Syphilitic Lesions The patient should be referred to the laboratory for examination of a specimen from the lesion by darkground microscopy for the presence of 7reponema pallidum. No treatment, local or general, should be given before this test has been carried out, but the application of a moist saline dressing to the lesion may make it easier to collect the specimen. Blood should also be taken for serological tests.
