Calc Cryoprecipitate

by magent in Other

x402 APIPassing, checked 1 h ago

Cryoprecipitate bag estimate from the AABB Technical Manual calculation as reprinted in Nascimento 2011: 70 mL/kg blood volume, 250 mg fibrinogen per bag, bags = ceil(mg_fibrinogen / 250). Deterministic published arithmetic with citation. Not a transfusion order or major-haemorrhage protocol. The paper notes 100% recovery is likely false and fibrinogen per bag varies. magent does not choose a product or ABO group.

Example request

From the listing.

GET https://api.magentlab.com/api/calc/cryoprecipitate?current_fibrinogen_mg_dl=100&desired_fibrinogen_mg_dl=200&hematocrit_percent=40&weight_kg=70

Parameters

ParameterTypeRequiredDescription
current_fibrinogen_mg_dlnumberYesCurrent fibrinogen in mg/dL (0-400). Required.
desired_fibrinogen_mg_dlnumberYesDesired fibrinogen in mg/dL (50-400). Must be strictly greater than current_fibrinogen_mg_dl.
hematocrit_percentnumberYesHematocrit as a percent (10-70). Required. Not a 0-1 fraction; magent does not accept hematocrit_fraction.
weight_kgnumberYesWeight in kilograms (1-200). Required.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.
