Blood Transfusion Threshold Calculator

Determine transfusion triggers for pRBC, FFP, platelets, and cryoprecipitate based on clinical context: hemoglobin, PT/INR, platelet count, and fibrinogen levels.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Determine transfusion triggers for pRBC, FFP, platelets, and cryoprecipitate based on clinical context: hemoglobin, PT/INR, platelet count, and fibrinogen levels

Each component has a specific meaning:

  • Clinical context: hemoglobin — The clinical context: hemoglobin recorded for the patient or scenario being assessed.
  • PT/INR — The pt/inr recorded for the patient or scenario being assessed.
  • Platelet count — The platelet count recorded for the patient or scenario being assessed.
  • Fibrinogen levels — The fibrinogen levels recorded for the patient or scenario being assessed.

Note: Interpret the transfusion threshold result against the clinical thresholds and context described above.

How to Use

Enter the clinical context: hemoglobin, PT/INR, platelet count, fibrinogen levels for the patient or scenario you are assessing. Determine transfusion triggers for pRBC, FFP, platelets, and cryoprecipitate based on clinical context: hemoglobin, PT/INR, platelet count, and fibrinogen levels. Use the transfusion threshold result to inform your clinical assessment.
