Normal hemoglobin values are related to the person's age and sex. Normal values may vary slightly between test systems, and which groups of doctors have determined normal values for their group of patients; however, the value ranges are close (vary by about 0.5 g/dl) for almost every group.ormal hemoglobin values are related to the person's age and sex.

CODIS Development and Design. The Federal Bureau of Investigation (FBI) has provided the law enforcement community with the Combined DNA Index System (CODIS), a national DNAâprofile matching service comprised of databases containing DNA profiles from crime scenes, convicted offenders, and missing persons. CODIS began as a pilot project in 1990.
What happens to DNA evidence? Once DNA is collected, there is a protocol for how the evidence is handled and used in an investigation. The evidence will be provided to law enforcement who may send it to a crime lab. The lab will analyze the material and develop DNA profiles that are unique to a specific person. The lab works with law enforcement officials to compare these profiles to the DNA of potential suspects. If the perpetrator is unknown, they may compare the DNA profile against a large database run by the FBI called CODIS, the Combined DNA Index System.
