Method 1: Using the @media At-rules. The @media rule is used to define different style rules for different media types in a single style sheet. It is usually followed by a comma-separated list of media types and the CSS declarations block containing the styles rules for target media. The style declaration in the example below tells the browser to display body content in 14 pixels Arial font on the screen, but in case of printing it will be in a 12 points Times font.
Serological tests may be performed for diagnostic purposes when an infection is suspected, in rheumatic illnesses, and in many other situations, such as checking an individual's blood type. Serology blood tests help to diagnose patients with certain immune deficiencies associated with the lack of antibodies, such as X-linked agammaglobulinemia.
One of those is a blood test that confirms whether a person is seropositive or seronegative. Being seropositive does not mean that you absolutely have RA; it does help determine conclusively that a person has the disease when other tests show a similar outcome. What Does it Mean to be Seropositive? To determine if a person is seropositive for RA, a doctor will order a blood test. The blood test is used to help medical experts find two proteins: rheumatoid factor (RF) and anti-CCP. When either of these proteins are present in the blood test it may indicate that RA is present in the body.
