Why is forensic serology important

It is important that these tests — either one of them — are carried out to prove that these stains are in actual fact blood; and, more importantly, human blood. Serology, in addition to examining and identifying blood, is used to identify and categorise semen, saliva, sweat and even human faeces.

This can be achieved in the instance of faeces as it is covered in a mucus membrane to enable expulsion from the body. Serology also has a use in proving if unlawful sexual intercourse has taken place; this has become a necessary element of forensic science given the rise in sexual assaults and cases of rape. The processes used by a Serologist can help time intercourse and also help prove that unlawful intercourse actually took place.

Visual Examination The first step in a serological examination is the documentation and visual examination of evidence. Confirmatory tests for semen Using compound microscopes, scientists search for spermatozoa , or sperm cells, on slides prepared from swabs, clothing, etc. Contact DNA Evidence found at the scene can be submitted for the collection of epithelial i.

Beyond Forensic Serology The Forensic Serology Unit works hand-in-hand with other units when further analysis is required. Other Services Crime Scene Assistance: Scientists assist crime scene investigators by bringing the capabilities of the modern forensic laboratory to the field. Finding and documenting blood residue Freshly dried bloodstains are a glossy reddish-brown in color.

Under the influence of sunlight, the weather or removal attempts, the color eventually disappears and the stain turns gray. Well, for starters, one thing that causes it to be yellow is a pigment called bilirubin. Bilirubin is made when iron-containing compounds in your blood called heme are broken down. Heme makes your red blood cells red and transports oxygen in your blood.

The color of platelets is a cloudy-yellowish color as seen in bags of donated platelets waiting to be transfused into a patient. A normal platelet count ranges from , to , platelets per microliter of blood. Having more than , platelets is a condition called thrombocytosis; having less than , is known as thrombocytopenia.
