This panel is the traditional hemogram plus platelet count which must now be reported with with hemograms according to current US re-imbursement rule The panel includes 2 different RDWs to accommodate the two different ways of reporting them. (Most automated instruments report as a percent ). The hemoglobin produced by the automatic counters does not use a counting method to generate the hemoglobin so we have used the fotometry version of hemoglobin in this panel.

Profile to report Blood Group and RhD data. In addition to the code element valuesets delivered from EU Laboratory we have added 3 supplement value sets: CH LAB-Report BloodGroup Antibody Screen Test Result, CH LAB-Report BloodGroup Antibody Result, CH LAB-Report BloodGroup Immunohematology Tests. These value sets have a candidate binding, i.e. they are candidates to substitute general value sets in some defined situations.

Renal function can be determined by laboratory measurement of serum creatinine, from which the estimated glomerular (eGFR_MDMR) filtration rate can be calculated. Further input parameters are age, race and gender.
Note: The MDRD equation is hardly used any more and is replaced by the CKD-EPI equation.
GFR Calculators:

Glomerular filtration rate (GFR) is considered the best overall index of kidney function; however measured GFR is not practical in the routine clinical setting. Estimated glomerular filtration rate (eGFR) is a suitable alternative and can be calculated for adults >= 18 years using an equation incorporating the patient's age, gender, and measured serum/plasma/blood creatinine only (eGFRcr) (this term) or both serum/plasma/blood creatinine and serum/plasma cystatin-C (eGFRcr-cys) LOINC: 98979-8. The serum/plasma/blood creatinine value is based on a measurement procedure that is traceable to the isotope dilution mass spectrometry (IDMS) reference measurement procedure for creatinine. The 2021 CKD-EPI equations used for eGFRcr and eGFRcr-cys do not have a race term as does the older estimating equations that they replace. https://www.nejm.org/doi/pdf/10.1056/NEJMoa2102953

This value set is used in the ChLabObservationBloodGroup profile. It contains results of Blood Group Antibodies (substance) coded with SNOMED CT. It is used in the ChLabObservationBloodGroup profile

This value set is used in the ChLabObservationBloodGroup profile. It represents atypical IgG antibodies prior to transfusion or during pregnancy. The screening test is designed specifically to detect IgG antibodies and some IgM antibodies (non ABO) may also be detected. Antibodies detected by the antibody screen should then be identified, and a titer performed if the antibody identified is considered to be clinically significant during pregnancy.

This value set is used in the ChLabObservationBloodGroup profile. It contains Laboratory tests related to immunohematology
