Accordingly, prognosis of occupational asthma is contingent on early diagnosis and the adoption of protective measures for rhinitis. Diagnosis
The different forms of rhinitis are essentially diagnosed clinically. Vasomotor rhinitis is differentiated from viral and bacterial infections by the lack of purulent exudate and crusting. It can be differentiated from allergic rhinitis because of the absence of an identifiable allergen. Prevention
In the case of infectious rhinitis, vaccination against influenza viruses, COVID-19 virus, adenoviruses, measles, rubella, Streptococcus pneumoniae, Haemophilus influenzae, diphtheria, Bacillus anthracis, and Bordetella pertussis may help prevent it. Management
The management of rhinitis depends on the underlying cause. For allergic rhinitis, intranasal corticosteroids are recommended. For severe symptoms intranasal antihistamines may be added. Pronunciation and etymology
Rhinitis is pronounced , while coryza is pronounced .Rhinitis comes from the Ancient Greek ῥίς rhis, gen.: ῥινός rhinos "nose". Coryza has a dubious etymology. Robert Beekes rejected an Indo-European derivation and suggested a Pre-Greek reconstruction *karutya. According to physician Andrew Wylie, "we use the term [coryza] for a cold in the head, but the two are really synonymous. The ancient Romans advised their patients to clean their nostrils and thereby sharpen their wits." See also

Low serum ferritin (see below)
Low serum iron
High TIBC (total iron binding capacity), although this can be elevated in cases of anemia of chronic inflammation. It is possible that the fecal occult blood test might be positive, if iron deficiency is the result of gastrointestinal bleeding; although the sensitivity of the test may mean that in some cases it will be negative even with enteral blood loss.As always, laboratory values have to be interpreted with the labs reference values in mind and considering all aspects of the individual clinical situation. Serum ferritin can be elevated in inflammatory conditions; so a normal serum ferritin may not always exclude iron deficiency, and the utility is improved by taking a concurrent C-reactive protein (CRP). The level of serum ferritin that is viewed as "high" depends on the condition. For example, in inflammatory bowel disease the threshold is 100, where as in chronic heart failure (CHF) the levels are 200. Treatment
Before commencing treatment, there should be definitive diagnosis of the underlying cause for iron deficiency. This is particularly the case in older patients, who are most susceptible to colorectal cancer and the gastrointestinal bleeding it often causes. In adults, 60% of patients with iron-deficiency anemia may have underlying gastrointestinal disorders leading to chronic blood loss. It is likely that the cause of the iron deficiency will need treatment as well. Upon diagnosis, the condition can be treated with iron supplements. The choice of supplement will depend upon both the severity of the condition, the required speed of improvement (e.g.
