4. Laboratory Diagnostic Tools

Test	Deficiency Investigated
Serum retinol	Vitamin A
Serum thiamine	Vitamin B1
Serum vitamin B12 and folate	B12 and folate deficiencies
CBC with MCV	Macrocytic (B12, folate) or microcytic anemia
Plasma vitamin C levels	Vitamin C
25-hydroxy vitamin D (25-OH D)	Vitamin D
Prothrombin time (PT/INR)	Vitamin K (if prolonged)

Note: Not all tests are readily available in all settings. Clinical judgment is crucial when labs are limited.

5. Diagnostic Categories

• Subclinical Deficiency: Lab indicators abnormal, no clear symptoms.
• Mild Deficiency: Early symptoms present, reversible.
• Severe Deficiency: Advanced clinical signs, risk of complications.

6. Integrated Diagnostic Strategy

• Step 1: Screen at-risk individuals through history and symptoms.
• Step 2: Confirm with laboratory testing when available.
• Step 3: Rule out other causes of symptoms (e.g., anemia, infection).
• Step 4: Initiate supplementation and dietary intervention.
• Step 5: Follow-up for clinical and laboratory improvement.
