A hive of activity.

Getting under control.

This is a time when things will be happening quickly. You will probably be in hospital for a number of weeks. Medics will be confirming the EGPA diagnosis and at the same time administering drugs to combat your high eosinophil levels. They will also want to ensure that your system is balanced so will take regular, probably daily, blood and other tests until things settle down.

Establishing degree of damage.

They will be checking various organs for damage, particularly the heart, kidney and lungs. Peripheral nerve damage is quite common, so a neurologist will probably assess and record the extent and degree of damage. You will be getting new medications, some may be intravenously administered for a short time.

Essential process.

It all sounds very frightening but this is an absolutely crucial moment in the presentation of EGPA and must be rigourous.

Tests you may have.

Blood tests.

Very straight-forward, simply a pin prick. If you feel faint at the sight of blood, don't look.

Ultrasound.

To look at arteries, heart and maybe other organs depending on your symptoms.[14] Non invasive, clean off the gel and you're done!

EMG and Nerve conduction.

An electromyogram (EMG) measures the electrical activity of muscles. Nerve conduction tests check the efficiency of the nerves in sending electrical signals.Both are used to check the degree of nerve damage. [15] A little uncomfortable, thats all.

Scans.

Imaging to look at various organs

Other tests.

There may be some more invasive, one off tests, depending on how EGPA has manifested itself

Types of imaging.

X-Rays.

X-Rays were discovered in 1895 and are used still, to take grey scale images.[16] They are best for looking at bone.

CT Scan.

CT Scan (CAT Scan), developed in 1970s. Uses many X-ray beams with lower radiation doses, along with heavy computer processing to made 3D images which can be sliced by the computer.[17] Tissue can be seen.

MRI Scan.

MRI also developed in the 1970s. Uses magnets instead of X-Rays so no exposure to radiation![18] Much more detailed images especially for soft tissues and even nerves.

MRA Scan.

MRA a type of MRI scanner for the heart and associated blood vessels.[19]
