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.
DNA is generally used to solve crimes in one of two ways. In cases where a suspect is identified, a sample of that personâs DNA can be compared to evidence from the crime scene. The results of this comparison may help establish whether the suspect committed the crime.
