DNA SCREENING

NON-LEGAL PATERNITY

Tested individuals include: 1 child, 1 mother, and 1 alleged father. (Note: Mother is not required to test but is recommended)

Testing provides a fast positive or negative result. Samples can be collected in the privacy of the donor's home, without the lab technicians being present. Results are released and reported to anyone listed on the Authorized Self Collection form. The Paternity Screen is not designed for legal purposes, rather it is an inexpensive way to find out the results before involving others.

 

COURT ADMISSIBLE PATERNITY TEST

Tested individuals include: 1 child, 1 mother, and 1 alleged father. (Note: Mother is not required to test but is recommended)

Give a statistical analysis of paternity, and can be presented as evidence in court. Samples are collected at our site or we can arrange to have a collection at another site. Strict chain of custody protocols governs their collection and transport to the lab. A legal affidavit/court order, photos, and valid identification is required or the test cannot be conducted. Results are reported to all individuals listed on the DNA release waiver form. Court admissible results report greater than 99.99% probability of paternity as a result of the statistical analysis that is performed after DNA testing.

 

When the Father is unavailable for testing, two testing options are available.

Grand Paternity Study:

Tested individuals include: 1 child, 1 mother, and both of the alleged father's parents

A Grand Paternity Study is a test between the child, mother, and both parents of the alleged father. It is a straightforward test when both his parents are available for testing and there is no doubt as to who his parents are. Since the mother and father of the alleged father each contributes half of their DNA to their child, we can "recreate" the alleged father's DNA make-up for comparison purposes by testing his mother and father. The turnaround time for this study is two to three weeks from the time all samples are received in the laboratory.

Siblingship Study:

Tested individuals include: 2 siblings with or without the mother. (With mother is strongly recommended)

The siblingship study can be performed to determine the probability of whether the tested parties are full siblings, half-siblings, or unrelated. With the mother's participation, the probability increases dramatically to usually over 99%. The turnaround time for this study is two to three weeks from the time all samples are received in the laboratory.

Full Siblings: Siblings who share the same mother and father
Half-Siblings: Siblings who have one biological parent in common, however the other biological parent is different.
Unrelated: Individuals who do not share any common biological parentage.

 

DECEASED INDIVIDUALS

Can be tested using medical, funerary, or abandoned biological materials. Often these are routine, but they may involve serious criminal charges and difficult-to-work-with samples. We have extensive experience and an outstanding, courtroom proven record with these cases. If the date of death is recent, call immediately to discuss the circumstances to prevent the loss of easily obtainable samples.

 

NEWBORN TESTING

Can be performed on samples obtained by trained medical professionals during the cutting of the umbilical cord at birth. Kits are sent out to either the individual or attending doctor prior to the delivery date.

 

TWIN ZYGOSITY

Is performed to determine whether twins are identical or fraternal. Samples are only required from the twins.

 

FORENSICS

IDENTITY TESTING

Is performed on children and high profile individuals to create a genetic identification profile in case of disappearance or foul play. This procedure is also performed to determine whether two samples are from the same individual.

 

CRIMINAL PATERNITY:

California DNA's Lab has the distinction, of having the highest appellate acceptance for an RFLP DNA criminal paternity. Our Lab has years of experience performing these cases and typically provide reports so convincing that further testimony is unnecessary.

 

BODY IDENTIFICATION:

This can involve direct comparison of tissues and other samples, and often requires the performance of "reverse paternity" calculations. California DNA's Lab has a track record with the unusual and sub-optimal samples often encountered under these circumstances is among the best.

 

DNA DATABANKING:

California DNA's Lab has profiles under contract on more than 25,000 individuals that are currently in law enforcement data banks, including the FBI's National DNA Index System. We are capable of performing this work by both of the FBI acceptable platforms and are currently implementing robotic systems to improve the efficiency of these procedures.

 

NO SUSPECT CASE WORK:

We contract with public sector crime laboratories to develop DNA profiles on evidence, primarily from sexual assaults, for whom law enforcement officials do not have viable suspects.

DRUG TESTING SERVICES

Hair follicle screening for drugs of abuse

Unlike other drug testing methods, hair follicle screening can provide an accurate look at an individual's drug usage over the course of a 90 day period. And the donor's ability to adulterate a hair sample is virtually nonexistent due to laboratory testing procedures, so there is little need to worry about inaccuracy due to sample tampering. About 120 strands of hair are cut as close to the donor's scalp as possible. The sample is then forwarded to our laboratory where it is chemically cleansed to remove any contaminants. The sample is then liquefied and tested. Because the test is so accurate and thorough, it is the chosen testing procedure of the Courts. In addition to private corporations we offer services to many Superior Courts and Attorneys, who come to us for their drug testing needs. Hair follicle screening is the most reliable drug testing method available.

Suspicious Substance Testing

At California DNA we can conduct testing on suspicious substances in order to make a determination as to what the substance is. We have the most advanced technologies that allow our lab to analyze various unknown substances. This ensures that, should you find a suspicious substance on an employee, a child or just in the vicinity of your office or home, you can get a true and accurate account of what that substance is.
