Diagnostic Tests for Foot ulcer
Diagnostic Test list for Foot ulcer:
The list of diagnostic tests
mentioned in various sources as
used in the diagnosis of Foot ulcer
- Examine the ulcer
- Site of ulcer - e.g. venous ulcers are usually found on the inner side of the lower third of the leg, but may occur lower down on the foot; arterial ulcers are found on the tips of the toes and over pressure areas; neuropathic ulcers occur over pressure areas.
- Shape and size
- Edge of the ulcer - e.g. the edge of a venous ulcer is usually sloping and pale purplish-blue in color; malignant change in a chronic venous ulcer causes a raised and thickened edge; syphilitic ulcer has a punched out edge; tuberculous ulcer has an undermined edge.
- Base - e.g. venous ulcer is usually covered by granulation tissue ( area of new vessel growth) and white fibrous tissue; arterial ulcers usually have no granulation tissue; syphilitic ulcers have a base that looks like leather.
- Depth of ulcer - e.g. venous ulcers are usually shallow and flat; arterial ulcers are often very deep and may penetrate down to bone and underlying joints; neuropathic ulcers are usually deep penetrating ulcers.
- Note amount and type of discharge from the ulcer - e.g. clear, bloody, pus-like, offensive, copious , slight.
- Physical examination
- Examine the whole leg for varicose veins (which may suggest venous ulceration as the cause of foot ulcer
- Examine lower leg for signs of chronic venous hypertension which indicates the presence of disordered venous blood flow - e.g. pigmentation, warmth, redness and tenderness.
- Examine the lower leg for signs of peripheral vascular disease which may indicate an the cause of the ulcer is due to an inadequate blood supply - e.g. skin pallor, coldness and lack of hair.
- Examine the lower leg for signs of peripheral neuropathy - e.g. lack of sensation over the surrounding skin.
- Palpate the peripheral pulses in the leg. If pulses are absent may indicate that the ulcer is due to inadequate arterial blood supply
- Examine the groin lymph nodes for enlargement which may indicate infection of an ulcer or malignant change in the ulcer
- Blood tests
- Full blood count to detect anemia
- Blood sugar (may diagnose undetected diabetes which can predispose to both arterial or venous ulcers)
- Syphilis serology if suspected
- Rheumatoid factor, ANA antibodies, ENA antibodies, dsDNA antibodies, antinuclear and anticentromere antibodies to diagnose possible causes of Raynaud's phenomenon
- Swab of any discharge form the ulcer if present
- Skin biopsy around the edge of the ulcer - if suspect cancer.
- Ankle brachial index - a quick screening test for peripheral vascular disease.
- Radiological investigations
- Doppler ultrasound scan can help define the severity of peripheral vascular disease
- Arteriography can define the site and degree of arterial obstruction in peripheral vascular disease
