In the setting of a normal chest radiograph, early ILD or pulmonary vascular disease or both can be present. This observation underscores the need for chest CT for confirming the diagnosis of ILD.[consultant360.com]
More hemoglobin is present in polycythemia, and so is elevated. In anemia, the opposite is true.[en.wikipedia.org]
Diffusing capacity may be low if a lung disease is present that causes the membrane to be thicker, for example, in diseases such as pulmonary fibrosis and sarcoidosis.[verywell.com]

Patients with methemoglobinemia most often have asymptomatic cyanosis. In severe cases, oxygen delivery is reduced to such a degree that symptoms of tissue hypoxia, such as confusion, angina, and myalgias, result.[msdmanuals.com]

Asthma, obesity, and less commonly polycythemia, congestiveheartfailure, pregnancy, atrial septal defect, and hemoptysis or pulmonary hemorrhage can increase Dlco above the normal range.[consultant360.com]
In congestiveheartfailure the reduction in DLCO may be secondary to interstitial oedema. Other causes of decreased DLCO are anaemia, renal failure, smoking and marijuana use.[analesdepediatria.org]
How the reduction in Dlco is interpreted can influence clinical decisions in patients with unexplained dyspnea or dyspnea that fails to improve with initial treatments such as bronchodilators. Variability in how Dlco is reported is a concern.[consultant360.com]

Respiratory complaints may be under-reported and/or unrecognized in RA patients with lung disease as individuals with RA are generally less physically active due to joint pain and chronic fatigue and thus less likely to experience symptoms such as dyspnea[hopkinsarthritis.org]
