Day 5: Labs Flashcards
What gets tested in the CBC and what does it mean?
- WBC: high (leukocytosis): infection
- Hemoglobin/Hematocrit (H&H): Hgb/Hct: low: anemia
- Platelets: Plt : low (Thrombocytopenia) : prone to bleeding
CBC with Differential adds:
- Bands (band cells): high (bandemia) : serious infection
- Segs (segmented neutrophils): high (left shift): acute infection
- Lymphs (lymphocytes): high: viral infection
- Monos (monocytes): high: bacterial infection
- Eos (eosinophils): high: parasitic infection
What does the BMP include?

BMP: Na
High (hypernatremia) : dehydration
Low (hyponatremia): dehydration
BMP: K
High (hyperkalemia): poor kidney function
Low (hypokalemia): prone to arrhythmias
BMP: BUN
high: renal insufficiency or failure
BMP: Creat
high: renal insufficiency or failure
What does the CMP include
BMP, T Prot/Alb, T bili, AST (SGOT), ALT (SPGT), Alk Phos
CMP: T prot/Alb

Total bilirubin: high: jaundice/liver failure
CMP: AST (SGOT)
Asparatate Transaminase: high: liver damage
CMP: ALT (SGPT)
Alanine Transaminase: High :liver damage
CMP: Alk Phos
Alkaline Phosphatase: high : liver damage
WHat does the cardiac enzyme panel include
Trop, CK, CK-MB, CK-RI
Cardiac Enzyme: Trop
Troponin: high: specific to heart damage
Cardiac Enzyme: CK
creatinine kinase: high: heart damage or Rhabdomyolosis
D-dimer test for and significance:
Tests for PE, if high you must order either CTA chest (check creatine first) or VQ scan to rule out PE
What are the respiratory labs?
BNP, ABG, VBG
Describe BNP:
B-type natriuretic peptide; high: CHF
Describe ABG:
Arterial blood gas; low pH: acidosis
High/Low HCO3: metabolic problem
High/Low pCO2: respiratory problem
Low pO2: hypoxia
Describe VBG:
venous blood gas; low pH: acidosis
High pH: alkalosis
The cardiac order set:
CBC, BMP, CK (CK-MB), Troponin, EKG, CXR
For whom will the cardiac order set be given?
Any adult complaining of chest pain
What are the ENT labs?
Strep, Monospot, Influenza A/B
What are the pancreatic enzymes?
Lipase (Lip): high: specific to pancreatitis
Amylase (Amy): high : possible pancreatitis
What are the inflammation labs?
CRP (c-reactive protein): high: active inflammation
ESR or Sed Rate (erythrocyte sedimentation rate) : high: active inflammation
What are the OB/GYN labs?
HCG, Serum HCG Qual, HCG Quant
HCG tests for:
Positive: pregnant, Negative: not pregnant
Serum HCG qual tests for:
positive: preg, negative: not preg
Serum HCG quant tests for:
how long they have been pregnant
If it gets higher, further along
if it gets lower or unchanged: failed pregnancy
What are the pelvic exam labs?
