SERI provides professional service that is focused on your case, with all the attention it deserves. We are a small laboratory, unwilling to reduce casework services to assembly line analysis and reporting. SERI scientists are as proficient at locating and identifying biological stains as they are at obtaining DNA profiles from the stains. We understand that high tech doesnít help if trace evidence goes undiscovered. Once the analysis is complete, our analysts are available for consultation which helps integrate the results and interpretations into the context of your case. Our ability to locate and evaluate biological material and produce DNA results on the material found are unsurpassed by any laboratory in the world. Turn-around time for casework at SERI is estimated in weeks, not months or years.
We routinely assist clients by designing an approach to their biological evidence which is guaranteed to provide the most effective and efficient ways to locate, identify and type limited stain material.
Body fluids such as blood, semen, saliva, urine and feces are frequently crucial evidence in criminal and civil matters. Our scientists are the experts providing assistance to legal and law enforcement professionals as well as corporations and private parties.
Technical advances in forensic biology have produced a new era in biological evidence analysis. The possibilities seem endless, but the complexity also seems nearly so. We pride ourselves on our ability to communicate not only the science, but the real, practical meaning of this highly technical information. SERI scientists are trained to assist clients by clarifying the meaning of analytical results in the context of an investigation or litigation. Nobody does practical forensics better than SERI.
Our forensic expertise, experience, education and skill makes SERI’s scientists the field’s best experts to advise you and provide answers to your questions.
SERI analysts examine your evidence in our modern, state of the art laboratory using an array of forensic techniques which include alternative light sources, sensitive chemical tests, immunoelectrophoresis and microscopic examinations. We are able to locate and identify biological stains on garments, weapons, vehicles and household items. The stains are then isolated and removed for further testing. Once the nature of the stain is established, further testing to determine the likely individual source of the stain becomes the analytical focus.
SERI scientists handle every item of evidence with meticulous care, insuring that we fulfill our commitment to provide the best custodial as well as analytical attention to every item from every case submitted to our laboratory.
SERI has been a provider of DNA testing since 1989. Our analysts have processed thousands of evidence samples in cases related to homicide, sexual assault, paternity, accidents, identifications and larceny of various stripes.
SERI has provided the forensic community with reliable Short Tandem Repeat (STR) DNA testing of biological samples since 1996. Analysts have processed thousands of evidence samples involving homicide, rape, paternity and other forensic cases using the core CODIS loci recognized as standard by the Federal Bureau of Investigation (FBI). Additional loci are also available in cases where more genetic information is necessary for identification.
STRs available from SERI are Profiler Plus™ and COfiler™ (CODIS 13 core loci), Identifiler™ (CODIS 13 core loci plus 2 additional loci) and Y-STRs.
In addition, we maintain the availability of HLADQa, PolyMarker and D1S80, all systems which were available and widely utilized by laboratories in the past. These older DNA technologies are frequently useful, and often necessary, in looking at new evidence in older cases where evidence samples are no longer available for testing with newer methods.
Standard STR testing can be supplemented with male-specific (Y-chromosome specific) STR testing. This testing only amplifies DNA found on the Y chromosome and is used as a resource for distinguishing a male contributorís genetic profile. SERI has provided clients with valuable genetic information in cases made difficult by special considerations such as:
- A low number of sperm are identified and a complete genetic profile using standard STR testing was not possible
- The need to obtain a male profile in the presence of an overwhelming amount of female DNA
- The need to obtain a male profile from vasectomized or aspermic males
- The need to distinguish a mixture of multiple male donors
This highly sensitive technique may be required to generate the necessary genetic information if STR analysis cannot be performed. Mitochondrial DNA sequencing is useful in cases where samples consist of hair shafts, bones, teeth or are highly degraded, aged or putrefied. Because mitochondrial DNA is inherited maternally, all relatives in the maternal lineage have the same mitochondrial DNA sequence. Because of this, mitochondrial sequencing provides less information about the source of DNA samples than does STR analysis.
Some samples in older cases require reanalysis utilizing the same conventional serology methods and markers used by the original testing laboratory. This is especially useful in cases where none of the original evidence remains or all of the evidence has been destroyed, and investigators need to compare the genetic profiles of newly developed suspects to the original case evidence results. SERI provides the following classical methods:
- ABO Typing
- Enzyme Typing
- Serum Protein Typing
Most laboratories are unable to maintain proficiency in these older techniques and SERI is pleased to be able to offer the service to those who need it.<top>
All of SERIís analysts are court qualified expert witnesses. Our scientists have provided effective testimony in trials in most states in the U.S. SERI experts have testified in criminal and civil matters for prosecution, plaintiff and defense attorneys. In addition to testimony, they are able to provide assistance in planning cross-examination of opposing experts.<top>
