Proposed increase to DSHS Newborn Screening Kit effective January 1, 2026

The Department of State Health Services (DSHS) Public Health Laboratory is revising laboratory testing and fees to meet business needs.

Effective January 1, 2026, the cost of paid newborn screening (NBS) kits increases from $68.63 to $94.81. Paid NBS kits, ordered on or after January 1, 2026, would be billed at the new price of $94.81. Additionally, the procedure name will be updated from “Newborn Screening Panel Test Kit (private pay) Fee” to “Newborn Screening Panel Test Kit (Insurance/Self-Pay) Fee.” The purpose of this increase will be for the addition of new conditions to the DSHS newborn screening panel and to support increased costs for operations.

Stakeholders may submit comments until December 31, 2025. To view complete details, visit the DSHS Laboratory’s Fee Schedule webpage.

Re-enrollment Required to Access the Clinical Chemistry Online Portal 

The Texas Department of State Health Services (DSHS) Public Health Laboratory updated the Clinical Chemistry Laboratory Information Management System (LIMS) on April 28, 2025. This change impacts Texas Health Steps (THSteps) and other providers who submit lead, hemoglobin, hemoglobin types, glucose, and lipid specimens, to the DSHS Public Health Laboratory.  

As part of this change, we have assigned all Clinical Chemistry medical providers a new 8-digit Submitter ID number. If your facility receives test results through the Clinical Chemistry online portal, Lab Online, you must re-enroll using your new 8-digit Submitter ID number to continue accessing online reports.  Your previous login credentials, linked to the 9-digit TPI number, are no longer valid.    

What You Need to Do to Avoid Disruption of Service: 

• Use your facility’s new 8-digit Submitter ID number found in Section 1 of the updated G-THSteps or G-1B specimen submission forms. 
• Download the Remote Data System forms from the Remote Data Systems page. 
  • Complete a Facility Agreement form, one per facility. 
  • Complete the Web User Agreement form, one for each end user.  
  • Email completed remote data system forms to remotelabsupport@dshs.texas.gov.

Incomplete Information on THSteps Shipping Label 

The Texas Department of State Health Services (DSHS) Laboratory recently sent out green United States Postal Service (USPS) shipping labels for placing on canisters that transport whole blood specimens for Texas Health Steps lead and hemoglobin testing. We discovered that these labels lack essential information, which may cause the USPS to deny shipment.  

To ensure acceptance of specimens for shipment, please write “EXEMPT HUMAN SPECIMEN” on the green USPS shipping label. These specimens are exempt under USPS Publication 52, Section 346.12d, which means the specimens are not classified as Division 6.2 infectious substances. However, these specimens must meet packaging requirements.  

Recommended Actions:  

1. Package specimens in the provided DSHS shipping canisters according to DSHS guidelines. Note: Variations of the USPS shipping labels are currently in use in the field.  
2. Write “EXEMPT HUMAN SPECIMEN” on the green USPS shipping label.  
3. Inform USPS Staff: When mailing these specimens, provide a clear indication that the package contains Exempt Human Specimens as defined in USPS Publication 52, Section 346.12d, which are exempt due to their non-infectious nature and proper packaging. 
4. Carry Documentation: It may be helpful to have a printed copy of this document or of the relevant regulation to provide clarification if needed. 
5. Ask to speak to the Postmaster if issues persist.  

We are actively working to correct the issue. We apologize for any inconvenience this may cause and appreciate your understanding and cooperation.

Tips to Prevent Clotted Specimens

The number one reason for the rejection of whole blood specimens is clotting. Clotting can happen during or immediately after specimen collection due to insufficient mixing and slow draw time.

Tips for preventing clotted specimens:

• Invert the blood collection tube 8-10 times to ensure the blood is in contact with the anticoagulant inside of the collection tube.
• Collect the required volume within 2 minutes.
• Occasionally tap the capillary tube while collecting the blood specimen.
• Avoid squeezing, milking, or scraping the finger during fingerstick collection.
• Avoid overfilling blood collection tubes. They have a specific amount of anticoagulant for the volume of blood as noted on the collection tube.
• For good blood flow, keep the patient’s arm below the level of the patient’s heart.

For questions, contact ClinicalChemistry@dshs.texas.gov

Tips for Shipping Whole Blood and Serum Specimens

As the temperature begins to rise, the Department of State Health Services Laboratory reminds all submitters of the following tips.

For Submitters that ship whole blood specimens through the US Postal Service:

• Drop off specimens inside the Post Office.
• Avoid leaving specimens in locations that are subject to high temperatures (i.e., metal lockboxes or mailboxes).
• Consider shipping specimens overnight with enough cold packs using a courier service.
• Do not freeze whole blood specimens.

For Submitters that ship serum specimens through a courier service:

• Serum-only samples for dyslipidemia and diabetes may be frozen and shipped overnight via courier
• Do NOT freeze serum separator tubes (SST) with serum samples.
  • Serum must be separated and placed into a transport tube before freezing.
  • Place enough cold packs/dry ice to ensure samples remain cold/frozen throughout shipment.

Do not ship serum specimens on Fridays or the day before the federal holidays.

For questions regarding this notice, email ClinicalChemistry@dshs.texas.gov.

Antimicrobial Susceptibility Testing for Neisseria Gonorrhoeae Now Available at the Texas DSHS Laboratory

Effective January 2023, Texas DSHS Austin Laboratory is accepting clinical swabs and pure isolates for Neisseria gonorrhoeae (GC) antimicrobial susceptibility testing (AST) in cases of suspected gonorrhea treatment failure.

Susceptibility to azithromycin, cefixime, ceftriaxone, and ciprofloxacin will be determined by the ETEST® gradient strip diffusion method. The GC AST may also serve as an auto reflex to the Lab’s GC culture testing. Results can be expected within 10 days of specimen receipt.

Acceptable specimens for GC AST are from patients who persistently test positive for gonorrhea after treatment (with or without symptoms) and for whom reinfection has been ruled out, or for disseminated gonococcal infections.

This GC AST service is free of charge to submitters. Specimen collection swabs and mailers for GC AST are provided free of charge by DSHS.

GC AST SPECIMEN SUBMISSION REQUIREMENTS FOR PROVIDERS AND LABORATORIES

• Clinical swabs and pure isolates from patients with suspected gonorrhea treatment failure or disseminated gonococcal infections are accepted.
• Swab specimens must be obtained using Copan ESwab™ Nylon flocked swabs with liquid Amies or Copan Transystem collection and transport kits.
• At least one visible isolate colony on chocolate agar slant or other appropriate media such as trypticase soy broth (TSB).
• Labeled specimens must be accompanied by a completed G-2B specimen submission form and copies of any previous related lab results.
• Specimen packaging and containers must be compliant with Category B Biological Substance, UN 3373 shipping requirements.
• All specimens may be shipped at ambient temperatures. If shipping temperatures are likely to exceed 28°C (~82°F), specimens should be packed with enough cold packs to keep them cold for up to 48 hours. Do not use dry ice.
• Ship swabs as soon as possible after collection. Specimens must be received by DSHS within one day of collection.

ORDERING FREE SWAB COLLECTION KITS AND MAILING SUPPLIES FOR GC AST

• DSHS Lab will provide specimen collection swabs, mailing containers, and UN3373 labels to the submitter upon request.
• Call (512) 776 - 7582 to request swab collection kits.
• DSHS does not provide supplies for pure isolate submissions.

Requesting GC AST on G-2B Specimen Submission Form (SECTION 5)

For Swab Specimens: Check “Neisseria” under the “Definitive Identification” column and write “GC AST” under the “Clinical Specimen” column.

For Isolate Specimens: Check “Neisseria” under the “Definitive Identification” column and write “GC AST” in the space next to it.

Testing and Specimen Submission Questions?

• Questions about AR Lab’s FedEx account and submitting GC specimens for culture and/or susceptibility testing may be sent to TexasARLN@dshs.texas.gov, or call (512) 776-7582.
• Submission guidance for GC AST at the DSHS Laboratory will be added to the Texas Antimicrobial Resistance (TX AR) Lab’s webpage soon.
• Details on how to use the AR Lab’s FedEx account to ship GC AST specimens will be added to the AR Lab’s specimen shipping webpage soon.

Labeling Guidelines for Texas Health Steps Hemoglobin and Blood Lead Specimens

All primary specimen containers must be clearly and legibly labeled with at least two patient-specific identifiers. The two identifiers on the specimen submission form must match exactly with the two identifiers on the specimen tube. Unidentified or improperly labeled specimens can delay testing and cause the specimens to be rejected.

Examples of Patient Labels

• Demonstrations of correctly labeled specimens
• Tips on how to meet the 2 ID requirement
