Ranges

Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ

  • BRAF Mutation Analysis 16767

    Tissue · Fasting not stated · Turnaround Set up: Mon, Thurs (a.m.)

    Method and collection
    Method
    Next Generation Sequencing
    Collection
    Do not reject specimens, send to laboratory for screening. For submission of paraffin block, tissue source and block ID are required on the requisition form. A pathology report must be submitted. For whole blood in EDTA specimens, sample type, collection time and date should be entered on tube and requisition form. Ship samples immediately to maintain stability. Ship samples room temperature or on ice pack in summer.

    Do not reject. Needle washings in alcohol-based fixative (e.g. Cytolyt ®) or formalin-fixed, paraffin-embedded tissue block FNA or FFPE specimens are acceptable for the assay. All specimens must be accompanied with pathology report. All FFPE specimens will be examined by a pathologist for confirmation and adequacy. Macrodissection, if warranted, is performed in the lab.

  • Thyroid, FNA Cytomorphology with Molecular Reflex 90818

    12 analytes · Needle washings in alcohol-based preservative (e.g. CytoLyt®) · Fasting not stated · Turnaround Set up: Mon-Fri (a.m.)

    Method and collection
    Method
    Cytomorphology Review • Reflex: Polymerase Chain Reaction-based Molecular Testing
    Collection
    ⁠⁠⁠⁠⁠⁠⁠DO NOT REJECT. Express a small portion of the FNA from needle directly onto glass slide and air dry or fix immediately by immersing in alcohol or by fixing with a commercially prepared cytology spray fixative. Label each slide with patient's name, pathology sample ID, and the number of needle pass (i.e., 1 for 1st, 2 for 2nd, etc). The needle should then be washed in a screw-cap vial of alcohol-based fixative (e.g. CytoLyt®) and labeled with patient's name, pathology sample ID and FNA location. FNAs from different locations (e.g., distinct nodules) should be collected individually on different slides and needle washings (e.g., A-left lobe, B-right lobe).

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
