Tell us about your casework DNA lab:

1.  Number of samples (serology and DNA extractions)?
 per year
2.  Number of cases?
 per year
3.  Number of analysts (criminalists)?
4.  Average salary of an analyst?

How much time does your lab typically spend:

5.  Checking that a reagent has been released for use and that it has not expired?
6.  Checking instrument maintenance logs to ensure maintenance was performed?
7.  Performing cross-contamination verification of all samples?
8.  Supporting in-house methods for managing samples and instrumentation?

Include tracking samples, batching, and generating scripts and sample sheets for instruments.

9.  Documenting cases?

Include chain of custody, sample documentation, profile interpretation and typing profiles into CODIS and PopStats.

10. Performing peer review?
11. Documenting that QC testing has been performed and verifying QA results?
12. Verifying inventory and ordering supplies?
13. Resolving troubleshooting incidents?
14. Preparing documents for legal proceedings?

Include depositions, discovery requests, and court cases.

15. Preparing for and conducting audits?

Include all internal and external audits, stop checks, QA, QA standards, and technical leader audits.


 Your calculated results

The potential increase in your lab's sample processing capacity is to samples/year and the potential increase in your lab's caseload is to cases/year, as shown in the table below. This is based on the results reported by other automated casework DNA laboratories.
