A

A–a Gradient

Rumus:
PAO₂ = FiO₂ x (760 - 47) - (PaCO₂ / 0.8)
A–a = PAO₂ - PaO₂

Adjusted Body Weight (AdjBW)

Rumus:
AdjBW = IBW + 0.4 x (BB aktual - IBW)

Alvarado Score

Nyeri berpindah ke perut kanan bawah (RLQ) Anoreksia (tidak nafsu makan) Mual / muntah Nyeri tekan di RLQ Nyeri lepas (rebound tenderness) Demam Leukositosis (↑ jumlah leukosit) Neutrofil batang meningkat (shift Left)

Interpretasi:
1–4: rendah
5–6: kemungkinan
≥7: tinggi (curiga apendisitis)

Anion Gap

Rumus:
AG = Na - (Cl + HCO₃)

BMI (Body Mass Index)

Rumus: BB / (TB²)

Body Surface Area (BSA)

Rumus (Mosteller):
√(BB x TB / 3600)
