Reflex testing is testing that is performed as a result of initial test results which are used to further identify significant diagnostic information required for appropriate patient care. The following is a list of the tests for which Laboratory Alliance may perform reflexive testing:
- ANA with Reflex - When the result of an ANA screen is positive, an ANA Evaluation Panel will be performed. The panel is composed of the following analytes: Anti-dsDNA, Anti-SSA, Anti-SSB, Anti-Smith, Anti-SmRNP, Anti-RNP, Anti-Chromatin, Anti-Scleroderma, Anti-Centromere B, Anti-Ribosomal P and Anti-Jo-1 (IgG antibodies). Note: If reflex testing is not desired, order “ANA Screen Only”.
- Syphilis Screen - If the result of a syphilis screen is positive, additional testing will be performed.
- Protein Electrophoresis - If an abnormality is identified on a protein electrophoresis, an Immunofixation and Quantitative Immunoglobulin are performed. Note: If reflex testing is not desired, order “Protein Electrophoresis – No Reflex”.
- Lyme Antibody – When the test for Lyme IgG/IgM is positive or borderline, a confirmatory test will be performed.
- Toxoplasma IgG/IgM – When the test for Toxoplasma IgG/IgM is positive, Toxoplasma IgM will be performed.
- Lipid Panel – When the result of triglycerides is greater than 300 mg/dL, a direct LDL is performed.
- Hep C Virus Ab – When antibody screen is positive and the signal/cutoff ratio is less than 8.0, additional testing will be performed.
- PSA with Reflex to Free PSA – When the result of the Total PSA is greater than 3.9 ng/mL and less than 10.1 ng/mL, a free PSA is performed.
- Thyroid Cascade – If the TSH is abnormal, a Free Thyroxine is performed. If Free Thyroxine is normal, then a Free T3 is performed.
- Cardiac Enzymes - If CK is greater than 55 U/L, CKMB will be performed.
- Platelet Count – If an automated platelet count cannot be obtained, a manual platelet count will be performed.
- Peripheral Smears – Peripheral smears and body fluids will be reviewed by a pathologist when indicated.
- White Blood Count – A manual white blood cell count may be ordered and performed if the automated white blood cell count cannot be resulted.
- Reticulocyte Count – A hematocrit may be ordered on a patient with the reticulocyte count test if the patient has not had a hematocrit or complete blood count performed within the previous eight hours. The hematocrit result is necessary to obtain a portion of the test result.
- Bone Marrow – A CBC/Diff and reticulocyte may also be performed.
- Lupus Anticoagulant – The following tests may also be performed when this test is ordered
- Dilute Russell Viper Venom – confirm and ratio
- APTT Mixing Study
- Dilute Russell Viper Venom Screen Mixing Study
- Dilute Russell Viper Venom Confirm Mixing Study
- Organism/Susceptibility Testing – If an organism is isolated, there may be additional identification and susceptibility testing done.
- Group A Strep Screen – When the results of a Group A Strep Screen are negative, a culture is done to confirm the negative.
- Viral Cultures – Additional charges for identification or screening for respiratory viruses may be added.
- Antibody Identification – is automatically performed if the antibody screen is positive unless the clinician indicated that further testing is not desired.
- Urine Microscopic – A urine microscopic analysis is performed when an abnormality on the screening examination is detected.
