WebThe AAFP Guidelines Panel recommends the following approaches for Group 2 cats: Further testing for FHT should consist of T4 and fT4 assays measured 2–4 weeks after the initial blood screening. A T4 value in the upper half of the reference interval combined with an elevated fT4 supports a diagnosis of hyperthyroidism.
WebThe free PAA in the buffer reduced the background in both cTnI and TSH immunoassays (compared to the control assay without free PAA). The limits of detection decreased from 2.1 ng·L−1 to 0.48 ng·L−1 in case of cTnI and from 0.070 mIU·L−1 to 0.020 mIU·L−1 in case of TSH if PAA is added to the buffer.
