Technologically Advanced Evaluations of Parentage in Tennessee and Nationwide

Collectech Services is a DNA specimen collection site that offers mobile collection services. We offer a wide array of sample testing, including DNA testing, non-invasive prenatal paternity test, post-mortem viability testing, and more, utilizing one of the well-known labs in the United States.

Non-Invasive Prenatal Paternity Test

After the 7th week of pregnancy, paternity can be determined with a simple blood draw of the parents. DNA detection is done using advanced technology to produce a blueprint that is unique to the mother, the fetus, and the alleged father. The blueprint comparison determines accurate paternity results close to 99.9%.

For the test, fetal DNA circulating in the mother’s blood is detected and analyzed using microarray SNP technology, comparing the markers between the child and the alleged father. The alleged father is considered the biological father when the test detects at least 99.9%.

Quick Facts About the Test

  • It uses fetal DNA released from placental cells into the mother’s blood, which undergoes a natural life cycle
  • As they grow older, they slough off and disintegrate, releasing fetal DNA into the mother’s blood.
  • We recommended that the client should wait until 7 weeks gestational age before getting this test done as the chances of detecting fetal DNA increases with the age of the fetus.
  • Because we are using free-floating fetal DNA, previous pregnancies will not affect this test. Fetal DNA does not last long in the mother’s blood after the baby is born.
  • A previous blood transfusion would not affect the test unless it was performed a week before the blood draw.
  • The risk associated with non-invasive prenatal paternity testing is no greater than any other blood draws on a pregnant woman.
  • This test does not provide any genetic information about the fetus.
  • The turnaround time is seven business days.
  • Expedited Services are available. Results can be delivered within 3 business days.

Accuracy-Related Clarifications

  • How accurate is the test?
    This is the most accurate non-invasive prenatal test available, gives 99.9% result.
  • What if I get an insufficient result?
    We recommend waiting a month for re-drawing the mother’s blood to rerun the test, although we don’t need to re-draw the alleged father’s sample.
  • Is it more accurate than an Amnio/CVS DNA test?
    When performed, an Amnio/CVS DNA test is equally as accurate, and the non-invasive testing does not pose any risk to the mother or the fetus.
  • 1 What’s the difference between this test and an amnio/CVS test?
    Blood is drawn from the mother’s arm and safer than other invasive collection methods like amniocentesis or CVS. It’s as safe as any blood collection from the mother’s arm. This test uses the very latest DNA technology and makes it possible to test the baby’s DNA from the mother’s blood. This test is very convenient. To perform Amnio/CVS, we schedule you at one of 5,000 sites we have available to collect the sample.

DNA Testing Paternity Testing

DNA Paternity Testing is the most reliable and powerful method for many reasons.

  • Answers difficult questions
  • Resolves disputes
  • Helps streamline court proceedings
  • Facilitates pre-trial settlements

Testing is based on a highly accurate analysis of the genetic profiles of the mother, child, and alleged father. Everyone is born with a unique genetic blueprint known as Deoxyribonucleic Acid (DNA) within each nucleated cell in the body that determines a person's genetic pattern and individual characteristics. A child inherits half of this DNA pattern from the mother and half from the father. If the mother's and child's patterns are known, the father's can be deduced with virtual certainty.

Types of Paternity Test

The DNA is passed down from mother and father to child, and a paternity test is a conclusive way to determine biological relationships.

Paternity Test (Trio)

A standard paternity test, called a trio, involves the child, mother, and alleged father, and mother’s participation is always encouraged in a paternity test.

Paternity Test (Motherless)

Because DNA testing is so powerful, paternity can be determined even when the mother is unwilling or unavailable to be tested.

Paternity Test with Related Alleged Fathers

If two alleged fathers are closely related (full brothers, half brothers, or father/son), they might share the same DNA markers commonly used in a DNA paternity test. Both could test positive as the child’s biological father.

Other DNA Testing Services

Grandparentage Test

The test is performed to determine a child’s relationship to the alleged father’s family when the alleged father is unavailable or unwilling.

Siblingship Test

Full siblingship & half siblingship provides the likelihood of a genetic relationship between two possible siblings. Grandparentage is more definitive than a siblingship test when the mother is not involved.

Twin Zygosity Test

Definitively shows if twins are identical or fraternal. The physician usually is able to tell whether they are identical or fraternal by examining the placenta.

Maternity Test

The test is performed to confirm the biological relationship between a mother and child in cases of immigration, adoption, and hospital nurseries.

Post-Mortem Viability Test

This test is performed on a sample from a deceased individual to determine if the sample yields sufficient viable DNA to proceed with further testing. The fee for the viability test is separate from the paternity test fee.

Genetic Reconstruction

It is done to test the relationship between a child and biological relatives of the alleged father.

Y-STR Test

Used to determine whether two or more males are related through their fathers.

Avuncular Test

Performed to determine if two individuals are related to each other as aunt-nephew or as uncle-nephew.

DNA Banking & Profiling

The procedure helps individuals to prepare for the future by preserving their genetic information.

What We Offer

We conduct the following tests and meet all DOT federal regulations outlined in 49 CFR part 40.

  • Individual
  • Employment
  • Federal
  • Court-ordered
  • School drug
  • Alcohol

The majority of the Fortune 500 companies get drug testing done with a purpose is to lessen the various harmful impacts of drug abuse in the workplace.

  • Tardiness
  • Absenteeism
  • Turnover
  • Attitude problems
  • Theft
  • Decreased productivity
  • Crime & violence

The U.S. Department of Labor estimates that drug use in the workplace costs employers $75 to $100 billion annually, and 65% of all accidents on-the-job are related to drug or alcohol and substance abusers utilizing 16 times as many health care benefits.

In 1987, SmithKline Beecham, found that 18.1 percent of all workers tested had positive results, and by 1997, the figure had dropped down to as low as 5.4 percent. Drug experts debate this means drug use has fallen, or drug abusers simply avoid employers that test. HR and safety professionals have found drug testing to be a valuable and cost-effective risk management tool.

Drug Testing Programs

The most common type of testing program is pre-employment. Courts have consistently upheld the legality of requiring a pre-employment drug test as a condition of employment. It is a best practice to obtain consent and to clearly indicate that drug testing is a requirement for employment.

For post-hiring testing, the employer should include training and education programs for supervisors and employees.

The company must publish guidelines for discipline in the event of a positive test, including random testing, individualized suspicion testing, post-accident testing, and testing that is legally required in certain industries, especially the Department of Transportation.

Although the Americans with Disabilities Act (ADA) and similar state laws provide protection for people who are in rehabilitation for drug addiction, the ADA does not protect people currently using illegal drugs and does not affect drug testing.

How Is the Testing Conducted

Drug testing is done by sending an applicant to the collection site to get a urine sample. The sample is then sent to a certified laboratory for analysis. Negative results are generally available within 24 hours. Instant test kits similar to home pregnancy tests are available and require the employer to manipulate a urine sample.

Although these tests are considered accurate for immediate screening, these are of no avail as laboratory confirmation, and retention of a sample for retesting be should be available. In addition, they are not any less expensive than laboratory tests.

The Ten & Five Panel Tests

Most employers utilize a standard five-panel test.

  • Marijuana (THC)
  • Cocaine
  • PCP
  • Opiates (codeine & morphine)
  • Amphetamines (including methamphetamine)

Some employers use a ten-panel test, which includes legal prescription drugs. Employers can also test for alcohol. Each drug and person is different, and most drugs will stay in the system for 2-4 days. For chronic users, results can be detected for up to 14 days, and even longer. Sedatives like Valium stay for up to 30 days. Through the hair testing method, drugs can be detected for 90 days.
Most employers will insist that a job applicant give the urine sample within a specific period so that a drug user does not wait until the drugs leave the system. Some drug experts consider a drug test to be an IQ test.

The Case of a Positive Test or Abnormal Test

Extensive procedures are done to re-confirm a positive test before reporting it. Most drug testing programs utilize an independent physician called a Medical Review Officer to review the results. The MRO will typically contact the subject to seek an explanation for positive results.

There can also be tests that are "negative' but show an abnormal result, such as a "low creatine level," which indicates a dilution of the sample. If the positive test is confirmed, the subject should have the right to pay for a retesting of the sample.

Urine samples for all positive tests are retained for that purpose.
If a current employee tests positive, then the employer must follow the policies and procedures they have put into place. Some employers will utilize an Employee Assistance Program (EAP) to arrange for professional assessment and treatment recommendations. All drug-testing results should be maintained on a confidential basis separate from an employees’ personnel file.


Pre-employment drug testing programs can be set up with ease. Firms that operate from a single location can usually turn to a local medical clinic for tests. For firms with multiple locations, programs can be set-up through drug testing agencies.

Drug tests for small to medium employers generally cost in the $50-$70.00 range.
