Describe how drug therapy is impacted by pharmacokinetics, pharmacodynamics, and pharmacogenetics. This free percent error calculator computes the percentage error between an observed value and the true value of a measurement. Procalcitonin (PCT) is a stable 116-amino acid precursor molecule to the hormone calcitonin. To the Editor. In this 2nd Pearl, we will discuss the quality requirements (i.e. Learning objectives of this February 2019 Pearl of Laboratory Medicine: Discuss the rationale for therapeutic drug monitoring (TDM). Medullary thyroid carcinoma (MTC) is a malignant tumor of the thyroid cells C cells, accounting for about 2–5% of thyroid cancers [].Calcitonin (CT), the main C cell secretory product, is considered a sensitive and specific marker for the diagnosis and follow-up of MTC [].However, CT assays suffer pre-analytic and analytic drawbacks: i. Procalcitonin (PCT) is a stable 116-amino acid precursor molecule to the hormone calcitonin. Fractional Carboxyhaemoglobin ± 2.0% . The intra-assay and total imprecision were tested by analysis of two control levels (0.342 and 10.4 ug / L) of human serum origin and one self-prepared serum pool. Fractional Methaemoglobin Total Error (TE) and Total Allowable Error (TEa) Total error and total allowable error are useful when choosing the SPC rule(s) to apply to a test. SOURCES: 1. Conclusion: The miniVIDAS PCT assay can be used for diagnostic purposes in clinical laboratories.

CLIA, CFR Part 439 a. Discuss analytical methods available for TDM Deming regression analysis of 1116 plasma or serum samples with PCT results detected across a dynamic assay range of 0.02–100 µg/L using the ARCHITECT PCT assay showed a good correlation with comparators ().In 322 samples from sites in Germany, South Africa and Vietnam, the ARCHITECT PCT assay compared with the Roche Cobas ® assay had a slope of 0.82 (95% … Introduction. the allowable total error, also known as TEa) used to define a patient result as unreliable. List various clases of drugs that require TDM. Fourteen (78%) out of the total eighteen patients with positive blood culture, showed median PCT concentrations greater than the cut-off values of 0.15 μg/L.
