Effective July 11: CHI Health Lab Will No Longer Offer a Serum H. Pylori Antibody Test
June 2016

The American College of Gastroenterology no longer recommends serology for detection of H. pylori infection. A positive serology only determines that a patient has been exposed to H. pylori at some time in the past, but not whether the patient is currently infected. Studies indicate that about half of patients with a positive H. pylori serology do not have active infection (ACG, 2007). Moreover, serology cannot be used to show that H. pylori have been successfully eradicated after treatment, as antibody levels commonly remain elevated for months to years after treatment.

The stool antigen test is recommended by both the American Gastroenterological Association (AGA) and the American College of Gastroenterologists (ACG) as the preferred non-invasive test for diagnosis and confirmation of eradication. The method is highly sensitive and specific and useful for diagnosis therapeutic monitoring, and test of cure.

See Helicobacter Pylori Antigen in the Lab Testing Directory for specimen requirements.

Maternal Screen (Quad Screen) Becomes a Send Out Test

Effective 4/01/2016, CHI will discontinue in-house testing for Maternal Screen (Alpha Fetoprotein, hCG, Estriol, & Inhibin). Specimens will be sent to PAML for Maternal Screen testing.

CPT Codes: 83605
Test Code: 0.4-2.0 mmol/L
Consult the Online CHI Health Lab Manual above for testing information.


Urine Culture Labeling Requirements

Proper and specific labeling of the source for urine specimens for culture is important because a
specimen collected by an invasive method (e.g. straight catheter) is processed differently, in
that more urine is cultured than for a clean-catch specimen.

  • Note that the specimens labeled simply as "urine" will be processed as a cleancatch.
  • Examples of appropriate specimen source labeling:
    • Urine, clean catch
    • rine, straight catheter
    • Urine, suprapubic aspirate

Interpretation Change: Methylenetetrahydrofolate Reductase (MTHFR) Mutation
October 1, 2015

Recently, the College of Pathology (CAP) has recommended that based on the current collective
literature studies, the interpretation comments for MTHFR testing should be modified.

CPT Code: 81291
Effective:October 1, 2015

Hyperhomocysteinemia has been indicated as a risk factor for arterial disease and venous thrombosis.
Homocysteine levels are affected by nutritional and genetic factors. Since 5, 10-methylenetetrahydrofolate
reductase (MTHFR) is involved in remethylation of homocysteine to methionine, patients with MTHFR gene mutations that reduce enzyme activities may develop hyperhomocysteinemia and thus be at elevated risk for vascular disease. Two common mutations in the MTHFR gene, 677C>T and 1298A>C, are detected in this assay. Read more...

ICD-10 Implementation October 1, 2015
September 14, 2015

On October 1, 2015, the United States transitions from ICD-9 to ICD-10 as the medical code set for medical diagnoses and patient hospital procedures.

ICD-10 numeric codes will be required for each test on the lab requisition at the time the test is ordered.
It is the responsibility of the ordering physician, nursing facility or clinic to provide clinically relevant ICD-
10 numeric diagnosis codes.

To comply with the CMS requirements without disrupting quality patient service and laboratory testing
you've long trusted us to provide, beginning October 1 we will follow the process outlined in this document.

Patient Instructions

CHI Health Laboratory provides routine adult and pediatric specimen collections for diagnostic testing and screening. In addition to routine blood collection, you may drop off other types of specimens, stool, urine and semen specimens for analysis.

Our skilled staff works diligently to provide each patient with prompt and professional service. We strive to make your experience at the lab as stress-free as possible with conveniently located facilities and hours of operation that accommodate your busy schedule. Our staff is committed to providing a professional environment for each patient during the specimen collection process. If you have any questions, please call our Customer Service Department at 402-717-5227 and we will be happy to assist you.

Where can I have my blood drawn or drop off a specimen?

CHI Health Laboratory offers primary and secondary patient service centers at many convenient metro Omaha and regional locations for specimen collection or drop off.

Patient Service Centers

We offer three Primary Patient Service Centers for your convenience. If you visit one of these centers, you will receive reference laboratory pricing.

Secondary Service Centers

As an alternative, you may visit one of the Secondary Service Centers located at hospital diagnostic centers to have your lab work drawn, or to drop off a specimen. Please bring with you a laboratory requisition. Click here for examples of laboratory requisitions accepted at the Primary and Secondary Service centers. 

What items do I need to take to the CHI Health Patient Service Center specimen collection lab?

You should bring with you the following information:
  • A laboratory requisition provided to you by your health care professional requesting laboratory testing. Click here to see examples of requisitions that can be submitted to the reference laboratory.
  • A current insurance card (Medicare, Private Insurance or HMO/PPO)
  • A photo ID (for example, a driver's license or state issued identification card) Minors must be accompanied by their parent or legal guardian.

    If you are bringing a minor to a specimen collection lab and you are not that minor's legal guardian, you may need to bring a notarized statement signed by a parent or legal guardian authorizing you to give permission for the collection and billing of the tests ordered by the minor's doctor.

Are appointments required?

Appointments are not required. Walk-ins are welcome. However, our locations are generally busiest from opening until 10:00 AM. If fasting is not required for your test, you may wish to come during off- peak hours.

What should I expect when I have a lab test?

Your role in the performance of a lab test is to provide a specimen that will be analyzed in a laboratory. The specimen you provide might be blood or urine or stool. You can be assured that CHI Health staff will make the specimen collection process as safe, quick, and comfortable as possible while safeguarding your dignity and privacy. When visiting your physician, ask what test is being performed, why the test needs to be done, what you can expect the procedure to be like, when you can expect to hear about your test results, and how the test results will affect the course of your care.

Do I need to do anything special to prepare for a lab test?

Sometimes special preparation is required to improve the accuracy of a test. This may involve fasting (not eating any or certain foods) for several hours or even overnight, drinking more or less water than usual, or avoiding certain medications or vitamin and herbal supplements before the test. If you are delivering a specimen to the lab, there might be special instructions for transporting the specimen. Your physician should provide you with written instructions for preparing for your test. Follow those instructions exactly as they are written. If you are not certain if special preparation is required, or if you have questions about the instructions you were given, contact your physician's office. If you did not follow the test preparation instructions you received from your physician, let the staff at the specimen collection lab know about this before your specimen is collected.
