Change in Reflex Urine Culture Criteria Urinalysis (UA) with Culture
September 1, 2015

  • Change refers to orders for urinalysis (UA) with culture, if indicated.
  • Sole UA criterium for performing a reflex urine culture is now dipstick leukocyte esterase positive (greater than trace) with greater than 10 WBC/high power field on microscopic exam.
  • All other criteria (odor, bacteriuria, etc.) are discontinued.
  • Rationale is to reduce unnecessary urine cultures with concomitant reduction in the inappropriate treatment of asymptomatic bacteriuria
  • Urinalysis and urine culture may still be ordered separately

  • New eGFR Equation and Reference Range
    July 21, 2015

    On July 21, 2015 the CHI Health Laboratory switched to an IDM-traceable Creatinine assay as announced in the July Lab Update. This prompted some confusion with the new estimated GFR (eGFR) equation and reference range.  Below explains why patients previously reported as > 60 ml/min and normal, will now flag as low unless > 90 ml/min.


    New Test Methodology: Creatinine
    July 21, 2015

    CHI Health Omaha labs including Schuyler, Missouri Valley and Corning will be switching to an IDM-traceable Creatinine assay.

    MICROBIOLOGY: BioFire Blood Culture “No Organism Detected” Results
    June 1, 2015

    The BioFire Blood Culture Identification system (BCID) is capable of detecting 24 microorganism targets, and 3 antibiotic resistance genes from a positive blood culture. Although these 24 microorganisms are the most commonly isolated pathogens from positive blood cultures, there are many organisms that may be present that cannot be detected by BioFire. Thus a result of “no organism detected” indicates a microorganism, not on the BCID target list, is growing in the blood culture. The identity of other microorganisms will be revealed by the conventional culture.

    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 Alegent 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.
