Biological Evidence Examination
Biological evidence may be recovered from a wide range of sources, including crime scenes, clothing, weapons, vehicles, bedding, personal belongings, and other objects.
Our services include the examination and assessment of biological evidence to identify material that may be relevant to an investigation and suitable for further forensic testing.
Blood and Bloodstain Evidence
Blood is one of the most commonly encountered forms of biological evidence in forensic investigations. Suspected bloodstains may be examined to determine their nature and, where appropriate, their suitability for further analysis.
Examination may include:
- Detection of suspected blood
- Identification of human blood, where applicable
- Examination of bloodstained exhibits
- Documentation of bloodstain locations and characteristics
- Selection and preservation of suitable samples
- Interpretation of biological findings within the case context
Body Fluid Examination
Biological evidence may consist of different body fluids or biological secretions. Appropriate forensic examination can assist in determining the nature of suspected biological material.
Depending on the evidence available, examination may involve:
- Blood
- Seminal material
- Saliva
- Vaginal secretions
- Other biological stains or cellular material
The examination approach depends on the type, condition, quantity, and preservation of the submitted evidence.
Sexual Assault Evidence Examination
Biological evidence can play an important role in investigations involving alleged sexual offences. Clothing, bedding, swabs, personal items, and other exhibits may contain biological material relevant to the investigation.
Forensic biological examination can assist in:
- Locating suspected biological stains
- Identifying relevant biological material
- Assessing samples for further forensic analysis
- Preserving suitable biological evidence
- Supporting subsequent DNA examination where appropriate
DNA Evidence Assessment
Forensic Biology and DNA analysis are closely connected areas of forensic investigation. Biological examination can help identify and prioritize samples that may be suitable for DNA profiling.
Our services may include professional assessment of biological exhibits and consultation regarding:
- Sample selection
- Biological evidence preservation
- DNA examination requirements
- Potential sources of biological material
- Interpretation of biological findings alongside DNA results
Hair Examination
Hair recovered from a crime scene or evidentiary exhibit may be examined for its physical and morphological characteristics.
Forensic hair examination may include assessment of features such as:
- Root characteristics
- Shaft characteristics
- Tip characteristics
- Pigmentation
- General morphological features
- Condition and appearance of the specimen
Where appropriate, suitable hair evidence may be considered for further laboratory examination, including DNA analysis where scientifically feasible.
