Umbilical Cord Announcements

Report Change Notification Report Change Notification


Effective July 18, 2016, USDTL will be implementing a new way of reporting quantitative results. In order to satisfy accreditation requirement, the concentrations of drugs exceeding the Upper Limit of Quantification (ULOQ) for any given drug will be reported as > ULOQ (greater than ULOQ). The ULOQ will be provided.

USDTL is now ISO/IEC 17025 Accredited USDTL is now ISO/IEC 17025 Accredited


We are proud to announce that we are the first laboratory in the world to be ISO/IEC 17025 accredited for drug and alcohol testing in umbilical cord, fingernail, and toenail specimens. On September 4, 2015, USDTL attained ISO/IEC 17025 accreditation showing full compliance with the international testing standards. We have received our accreditation from ANSI-ASQ National Accreditation Board, demonstrating technical competence in the field of forensic testing. The scope of our ISO/IEC 17025 accreditation encompasses all specimen types and methods of analysis utilized in our laboratory.

Improved Screening Assay For Buprenorphine in Umbilical Cord Improved Screening Assay For Buprenorphine in Umbilical Cord


USDTL has succeeded in improving their umbilical cord screening assay for buprenorphine by reducing the positive result cutoff from 1.0 ng/g down to 0.5 ng/g. The improved umbilical cord buprenorphine assay gives the best possible detection of buprenorphine exposure, making it possible to identify more newborns exposed to buprenorphine in utero.

Umbilical Cord FAQs

*Click the green and white plus sign beside each question to view the answer.

Can a hair test be manipulated by the donor?

Yes. Bleaching, perming, dyeing and straightening can affect the outcome of a hair test. Cosmetically treated hair should not be collected.

Can you test for alcohol exposure in umbilical cord?

Yes, alcohol exposure can be tested individually or by adding the Umbilical Cord Testing EtG add-on to any of the Umbilical Cord Testing drug panels. The EtG add-on screens for Ethyl Glucuronide, a direct alcohol biomarker, indicating exposure to ethanol (drinking alcohol).

Does Umbilical Cord Testing use umbilical cord blood or umbilical cord tissue?

Umbilical Cord Testing uses 6 inches of umbilical cord tissue that has been drained and patted dry.

Have results been used in court cases?

Yes, the analysis of a number of tissue types for the presence of drugs of abuse has been used in every state for decades. Specifically, our umbilical cord testing has been used to provide evidence of drug use by the mother in numerous states. Additionally, the detection of drug in umbilical cord was used as evidence of maternal drug consumption in a murder case in South Carolina and that interpretation was upheld on appeal to the SC Supreme Court.

How long does the laboratory keep remaining umbilical cord tissue?

Negatives are kept for 1 week, and positives are kept for 1 year.

How should umbilical cord tissue be stored?

The sample is stable at room temperature for 7 days, can be refrigerated (2-8° C) for up to 3 weeks and frozen (< -10° C) up to 1 year.

Is umbilical cord genetically fetal tissue or tissue of the mother?

The fetus generates umbilical cord during the first five weeks, therefore, it is fetal tissue.

May the reported quantitation of drug or metabolite in hair, nail, meconium, umbilical cord, or urine be used to determine the timing of the drug use, how often the donor uses the drug, or the extent of the donor’s drug use?

No. When testing a reservoir specimen type, a specimen type where analytes tend to accumulate, you may not backtrack to determine time, dosage, or frequency. The result is positive or negative for the appropriate detection window associated with the specimen type.

The umbilical cord was fixed in formalin. May it still be used for the Umbilical Cord Testing?

No, Umbilical Cord Testing has not been validated for tissues that have been fixed in formalin.

What is the window of drug exposure for umbilical cord tissue?

Dose/response studies have not been performed and will most likely never be performed for ethical reasons. However, when compared to meconium, which has a detection window of up to 20 weeks, Umbilical Cord Testing has demonstrated an agreement greater than 90 percent.

When will I receive umbilical cord results?

Test  Negative Result Positive Result
Umbilical Cord Drug Panel 1 working day 2 working days
Umbilical Cord EtOH 2 working days 3 working days

Why is Umbilical Cord Testing becoming the gold standard in newborn testing over meconium?

USDTL’s umbilical cord tissue testing is groundbreaking in newborn toxicology because it solves several problems:

  • Every newborn has an umbilical cord; meconium is not available for every birth.
  • Umbilical cord collection is a one-step procedure; meconium collection requires cumulative collections.
  • Umbilical Cord Testing offers improved positivity rates for Methamphetamine, Benzodiazepines and Opiates.
  • Umbilical Cord Testing improves the integrity of the chain-of-custody: only one donor and one collector are present during the collection. Meconium has multiple collections and multiple collectors.
  • Umbilical Cord Testing improves turnaround time because umbilical cord is ready for transport a few minutes after the birth, while meconium passages can be delayed for days before being sent to the lab.

Why was the mother's urine positive and the umbilical cord tissue / meconium negative?

There are several explanations for this. Different specimen types have varying thresholds for positivity. For example, a single dose of methamphetamine 12 hours prior to collection is highly likely to produce a positive urine result. However, it would be less likely to generate a positive result for a specimen type with a longer detection window such as umbilical cord, meconium or hair.
