Answers to Common Service Questions

What Clients in Teaneck Typically Want to Know

Mobile Lab Techs provides on-site specimen collection for drug and alcohol testing, DNA paternity and relationship testing, and immigration DNA testing. Clients often ask about what's included in each service, how long results take, and what the process looks like when we arrive at your location.



Below are answers to the questions we hear most frequently about workplace compliance testing, DNA collection procedures, turnaround times, and how Mobile Lab Techs coordinates with laboratories and employers.

  • How does mobile phlebotomy work for home visits?

    A certified phlebotomist travels to your home, office, or preferred location to collect blood samples using sterile equipment. The specimen is then transported to a laboratory for analysis. At MOBILE LAB TECHS, we offer 24/7 scheduling to accommodate your availability throughout Bergen County.
  • How long does DNA paternity testing take to get results?

    Most DNA paternity results are available within 2 business days of laboratory receipt.  Results are typically delivered through a secure online portal. At MOBILE LAB TECHS, we provide accurate molecular diagnostic services with quick turnaround times for genetic analysis.

  • Can drug and alcohol testing be done at our workplace?

    Yes, on-site workplace testing brings certified technicians directly to your business location to conduct screening for employees. This service ensures compliance with legal and safety protocols while minimizing employee downtime. MOBILE LAB TECHS serves businesses throughout Teaneck and surrounding Bergen County areas.
  • What's the difference between pre-employment and workplace drug screening?

    Pre-employment screening occurs before hiring to assess a candidate's health and drug-free status, while workplace testing monitors current employees for ongoing compliance and safety.

  • What specimens can be collected for laboratory testing?

    Professional specimen collection includes blood draws, urine samples, saliva, and other biological samples depending on the diagnostic test required. Each sample is collected using sterile techniques and proper handling protocols. At MOBILE LAB TECHS, we ensure accurate collection for reliable medical diagnostics.
  • Do I need to prepare before a mobile blood draw?

    Preparation depends on the specific test ordered by your physician. Some blood tests require fasting for 8 to 12 hours, while others have no special requirements. When scheduling with MOBILE LAB TECHS, we'll provide clear instructions based on your laboratory order.
  • How quickly can I access my lab results online?

    Most laboratory test results are available through a secure online portal within 24 to 48 hours, though complex tests may take longer. The portal provides convenient access to diagnostic reports as soon as they're validated by the laboratory.
  • Is mobile radiology available in Bergen County locations?

    Yes, mobile radiology and ultrasound services deliver accurate imaging directly to patient locations throughout Bergen County, including Teaneck, Hackensack, and Englewood. This service is ideal for patients with limited mobility or those requiring convenient on-site diagnostic imaging.
  • What workplace compliance testing do employers need? 

    Most employers need pre-employment screening, random testing, and post-accident and reasonable-suspicion testing. Employers with DOT-regulated drivers also need a random testing pool meeting FMCSA minimum rates. Mobile Lab Techs provides on-site collection for all of these, and runs a DOT random testing consortium for owner-operators and fleets. 


    These services ensure regulatory compliance, workplace safety, and legal protection. MOBILE LAB TECHS provides comprehensive on-site solutions for businesses in New Jersey.

  • Can mobile lab services accommodate urgent or after-hours requests?

    Yes, mobile phlebotomy and specimen collection are available 24/7 with flexible appointment scheduling. This allows patients and businesses to arrange testing outside standard office hours for emergencies or convenience. At MOBILE LAB TECHS, we adapt to your schedule throughout Bergen County.
  • Do you provide DOT physicals? 

    A DOT physical must be performed by a medical examiner listed on the FMCSA National Registry. Call 866-242-3826 and we'll tell you whether we can schedule one for you or refer you to a certified examiner nearby. We do provide the full range of DOT drug and alcohol collections, on site at your location. 

  • Do you provide immigration DNA testing?

    Yes. Immigration DNA testing establishes a biological relationship for a visa or green card application, and requires documented chain of custody at collection. We collect the samples and manage that documentation. Note that this is separate from the USCIS immigration medical exam, which must be performed by a designated civil surgeon — we do not provide that exam. 

  • Does Mobile Lab Techs perform the laboratory testing?

    No. We are a collection and transport service. We collect your specimen, document and transport it under controlled conditions, and deliver it to our partner laboratory, where the testing is performed and results are reviewed by board-certified physicians. Keeping collection and analysis separate is standard practice and part of what makes a result defensible. 

  • How does pricing work?

    We accept most major insurance plans and verify coverage before your appointment. For self-pay and employer accounts, we quote in writing up front — collection fee, travel and any add-ons — so the invoice matches the quote.

  • Where do you perform collections? 

    Mobile Lab Techs comes to your location—workplace, residence, job site, terminal or any address you specify. We bring the collection materials, perform the procedure on-site, and transport specimens to the laboratory under chain of custody.

  • What should I bring to a DNA collection appointment? 

    You do not need to bring anything. Mobile Lab Techs provides all collection materials and completes the required documentation on-site. If the test is for legal or immigration purposes, we manage the identity verification and chain of custody records as part of the service.

  • Can you collect samples from multiple people at the same appointment? 

    Can you collect samples from multiple people at the same appointment? Yes. If the test requires samples from a child and alleged father, or multiple family members for immigration DNA testing, Mobile Lab Techs collects all participants during the same visit and ensures each sample is documented and tracked separately.


  • What is included in a standard drug test collection? 

    A standard urine drug screen collection includes specimen collection in a sealed container, temperature verification, documentation of donor identity, tamper-evident sealing, and transport to the laboratory under chain of custody. If the test is DOT-regulated, the collection follows additional federal custody and control form requirements.
