Measurement of thyroid hormone T4 (thyroxine) by chemiluminescence.
Measurement of pregnancy specific binding protein (PSBP) by ELISA. Results aid in confirmation of pregnancy in ruminants. This test is validated for cattle, small ruminants, bison, and buffalo. PSBP is produced after 28 days gestation in cattle, after 30 days of gestation in small ruminants, and after 40 days of gestation in buffalo/bison.
Measurement of relaxin by Rapid ImmunoMigration. In dogs, relaxin can be detected as early as 22 days of pregnancy, with the highest concentrations occurring at 42-56 days of pregnancy. In cats, relaxin can be detected as early as 25 days but more reliably after 31 days of pregnancy.
Detection of thyroglobulin autoantibodies (TgAA) by ELISA.
Tracing of albumin and globulin fractions by gel electrophoresis. Includes alpha 1, alpha 2, beta 1, beta 2, and gamma protein concentrations and pathologist interpretation, when indicated.
Measurement of fibrinogen concentration by heat precipitation.
Measurement of serum and urine creatinine, sodium, potassium, chloride, calcium, and phosphorus by automated analyzer to determine electrolyte fractional excretion.
Measurement of sodium, potassium, and chloride by automated analyzer.
Detection of infectious agents (i.e. Hepatozoon spp., bacteria, spirochetes) and neoplastic cells (i.e. mast cells) by microscopic evaluation of the buffy coat.
Detection of IgG, IgM or C3 on erythrocytes via direct antiglobulin test (direct Coombs test); measurement of WBC, RBC, HGB, HCT, MCV, MCH, MCHC, RDW, reticulocytes, PLT, PCT, MPV; and microscopic blood smear review for WBC differential, cellular morphology, and hemoparasites. A positive Coombs can support the diagnosis of immune-mediated hemolytic anemia (IMHA) when compatible clinical…
