Investigations of
endogenous Eczema:
Skin swabs should be taken in case there is suspicion of
secondary bacterial or viral infection.
The swab should be dipped in
the transport medium before being applied to the affected skin.
Note should be made of type
of bacteria detected and their culture and sensitivity.
Skin scrapings canbe taken
in case a fungal infection is suspected.
Nasal swabs are useful to
exclude nasal staphylococcal carriage.
Blood Tests may reveal a
raised level of Immunoglobulin E IgE.
RAST test would show
specific igE levels against various allergens such as house dust mite,pollens
etc.
Skin Biopsy maybe useful in
doubious diagnosis.
