Complete Blood Count
A basic blood test that reveals infection, anaemia and how well your body can repair a wound.
Key Takeaways
- A rising white cell count often signals infection before fever appears.
- Anaemia slows wound healing, and it is common in diabetes with kidney involvement.
- Platelet levels matter before any surgical procedure on the foot.
- Results are usually available the same day at our Surat clinic.
What Does a Complete Blood Count Show?
Complete blood count: a blood test measuring red cells, white cells and platelets, used to detect infection, anaemia and clotting capacity.
White cells rise when the body fights infection, so a high count supports the diagnosis of an infected ulcer. Red cells and haemoglobin show whether oxygen delivery to the wound is adequate, since healing tissue needs oxygen more than anything else. Platelets indicate clotting ability before surgery.
Why Is It Ordered for a Foot Wound?
Because a diabetic foot infection often hides. Fever may be absent, pain may be missing due to neuropathy, and the wound can look deceptively small. Consequently, blood results add objective evidence to what the eye sees.
Furthermore, anaemia is common in long standing diabetes. A wound simply cannot close properly when haemoglobin is low, so correcting it becomes part of the treatment plan rather than an afterthought.
How Is the Test Done?
A small blood sample is taken from the arm and processed at our laboratory. Fasting is not required. Results are typically ready the same day, so treatment decisions are not delayed.
What Happens After the Result?
High white cells with a spreading wound usually means antibiotics start immediately, often alongside debridement. Anaemia is investigated and corrected. Normal results are equally useful, because they help rule infection out and support a conservative plan.
What Does the Test Cost?
A complete blood count is among the least expensive investigations we run, and it is usually bundled with other wound tests to keep the total low. Charges are confirmed before the sample is taken.
Expect a small needle prick, a short wait and a clear explanation of what the numbers mean for your wound. We go through the report with you rather than simply handing it over, since a raised white count changes the plan immediately.
