A comprehensive clinical examination is the basis for selecting further diagnostic steps:

  • General physical examination – including blood pressure, pulse, body temperature, body weight, body height; further:
    • Inspection (viewing) [anemia (anemia); lymphadenopathy (lymph node enlargement); edema (water retention in tissues)]
      • Skin, mucous membranes and sclerae (white part of the eye).
      • Abdomen (abdomen)
        • Shape of the abdomen?

    • Auscultation of the lungs
    • Abdominal (stomach) examination [peritonitis (peritonitis)?, hepatosplenomegaly (liver and spleen enlargement)?]
      • Percussion (palpation) of the abdomen.
        • Meteorism (flatulence): hypersonoric tapping sound.
        • Attenuation of tapping sound due to enlarged liver or spleen, tumor, urinary retention?
        • Hepatomegaly (liver enlargement) and/or splenomegaly (spleen enlargement): estimate liver and spleen size.
