From Heather DeVries, Indiana University Health: Greetings George! One of the facilities in our system is questioning our critical fibrinogen level. Anything <70 mg/dL is considered critical, and they would like to know why we don’t use a cutoff of 100 mg/dL. Our current level was established before I came to IU Health, and our pathologist is not sure where it is from. I wonder what other laboratories are using? Many thanks and hope you are well, Heather
Hello, and thank you, Heather for your question. Just posting to learn what others are using as a critical cutoff.
Most guidelines suggest
Most guidelines suggest either 100 mg/dL (1g/L) or 80 mg/dL (0.8g/L) – Reference: Lippi G, Adcock D, Simundic AM, Tripodi A, Favaloro EJ. Critical laboratory values in hemostasis: toward consensus. Ann Med. 2017;49:455–61.
