Posted January 8, 20187 yr comment_72023 Hi, I just want to make sure my interpretation of counting tests for CBCs is correct. CLIA says For complete blood counts, each measured individual analyte that is ordered and reported is counted separately. So for example, if we did 100 CBCs, and we're counting WBC, RBC, Hgb, MCV, RDW, Plt count, Neut, lymph, mono, eos, and baso (11 tests) it's reported as 1100? Thank you in advance. Rachel
January 9, 20187 yr comment_72043 What CLIA rule is this under? What are you counting tests for? (You better not be billing those individual tests separately!) Even if it is just for workloading, i would think that a CBC would be one test--but I may be wrong there. Scott
January 11, 20187 yr Author comment_72092 Hi Scott, Billing is an entirely different matter than counting tests for CLIA. Refer to page 9 of CMS form 116. For hematology then, hematocrit and MCHC are not counted because they are calculated, not measured. Thanks, Rachel cms116.pdf Edited January 11, 20187 yr by astridfeline add example.
January 11, 20187 yr Author comment_72093 Also, CLIA certification fees are dependent on test volume.
December 31, 20195 yr comment_79291 For annual test volume, you're counting the measured components of the CBC separately - WBC, RBC, PLT, Hgb, MCV - but the differential itself is one test. So one CBC is actually 6 tests. Calculated parameters like RDW don't count towards the total.
