  2. Rheumatoid factor - Wikipedia

    en.wikipedia.org/wiki/Rheumatoid_factor

    The sensitivity of RF for established rheumatoid arthritis is only 60 to 70 percente with a specificity of 78 percent. [8] Rheumatoid factor is part of the 2010 ACR/EULAR classification criteria for rheumatoid arthritis. RF positivity combines well with anti-CCP and/or 14-3-3η to inform diagnosis. [9]

  3. Rh blood group system - Wikipedia

    en.wikipedia.org/wiki/Rh_blood_group_system

    Rh(D) status of an individual is normally described with a positive (+) or negative (−) suffix after the ABO type (e.g., someone who is A+ has the A antigen and Rh(D) antigen, whereas someone who is A− has the A antigen but lacks the Rh(D) antigen). The terms Rh factor, Rh positive, and Rh negative refer to the Rh(D

    [21] [74] [82] As a result, LT 4 monotherapy may not result in a "truly biochemically euthyroid state." [22] Patients may express a preference for "low normal or below normal TSH values" [82] and/or T 4 and T 3 monitoring. The monitoring of other biomarkers that reflect the action of thyroid hormone on tissue levels has also been proposed. [15 ...

    Factor XII (Hageman Factor) Liver: A protein that circulates inactively, until activated by collagen, platelets, or exposed basement membranes via conformational change. When activated, it in turn is able to activate three plasma systems involved in inflammation: the kinin system, fibrinolysis system, and coagulation system. Membrane attack complex

  6. Pearson correlation coefficient - Wikipedia

    en.wikipedia.org/wiki/Pearson_correlation...

    Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.

  7. APS-C - Wikipedia

    Sensor sizes range from 20.7×13.8 mm to 28.7×19.1 mm, but are typically 22.3×14.9 mm for Canon and 23.5×15.6 mm for other manufacturers. Each variant results in a slightly different angle of view from lenses at the same focal length and overall a much narrower angle of view compared to 35 mm film .

    COVID-19 symptoms range from asymptomatic to deadly, but most commonly include fever, sore throat, nocturnal cough, and fatigue. Transmission of the virus is often through airborne particles . Mutations have produced many strains (variants) with varying degrees of infectivity and virulence . [ 9 ]
