Unit 5: Biomedical Science deck, 29 slides
What’s in it:

Introduction (4 slides): the box key, the three learning aims, and the PSAB.
A: Haematology (8 slides):
Blood components, and plasma vs serum.
A full blood count table: typical adult ranges and what low or high results may suggest.
Red cell disorders (iron deficiency, sickle cell, thalassaemia, malaria) with the key test for each.
White cell disorders (HIV, glandular fever, leukaemia, lymphomas), syphilis and hepatitis B antibody tests, and MDS.
The clotting cascade with haemophilia A and B and PT/INR.
Seven diagnostic techniques, including bone marrow aspiration.
An “Explain” model interpreting a blood result.
B: Histology and screening (5 slides):
Sample types (CSF, cervical, breast, prostate, autopsy), with consent and bacterial meningitis CSF findings.
Six steps of tissue processing (fix → embed → section → H&E stain → examine).
The four screening programmes in the spec (bowel, cervical, aortic aneurysm, newborn blood spot).
Implications of results: timely diagnosis, false positives and negatives, and costs.
C: Urinalysis (8 slides):
Normal urine, and a table of six conditions with their urine changes and why.
Six steps for collecting a sample (mid-stream, timing, storage).
A test strip table giving the mechanism and accuracy factors for each pad.
Specific gravity, microscopy and when to use each test type.
The C.P6 practical procedure.
Home vs clinical urinalysis for C.D3.
Review (4 slides): an assignment plan, the criteria at a glance, a confidence tracker and a “Well done” slide.
