Which of the following disciplines typically has the fewest service requests?

The discipline of latent prints typically has the fewest service requests compared to the other options listed. Latent print examination involves the analysis of fingerprint impressions that are often found at crime scenes and require careful and detailed examination to identify individuals.

One reason for the lower volume of service requests in latent prints is that the collection and submission of latent print evidence may depend on specific types of crimes, such as burglaries or violent offenses where fingerprints may be left behind. In contrast, disciplines like forensic biology, controlled substances, and toxicology are often involved in a wider array of crime types, including drug-related offenses and various biological examinations, leading to more frequent service requests.

Moreover, the process of collecting viable latent prints is more complex and may be less common than other types of evidence collection, resulting in fewer cases being submitted specifically for latent print analysis. As such, those working in this field may find that their workload is less intense in terms of the number of service requests compared to their counterparts in the other disciplines listed.
