Selected coagulation reference values for adult and juvenile baboons

Area of Science:

• Veterinary Medicine
• Primate Research
• Hematology

Background:

• Baboons are valuable models in biomedical research, particularly for studying hemostasis and thrombosis.
• Establishing species-specific reference ranges for coagulation parameters is crucial for accurate interpretation of experimental data.
• Limited data exists on normal coagulation profiles across various ages in baboons.

Purpose of the Study:

• To determine the normal ranges for prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen levels in clinically normal baboons.
• To provide baseline hematological data for baboons of different ages.
• To support the use of baboons as preclinical models in hemostasis research.

Main Methods:

• Blood samples were collected from 61 clinically normal baboons of varying ages using sodium citrate as an anticoagulant.
• Prothrombin times (PT) were measured using established laboratory techniques.
• Activated partial thromboplastin times (aPTT) and quantitative fibrinogen levels were determined using widely available assays.

Main Results:

• The study determined the arithmetic mean values and observed ranges for PT, aPTT, and fibrinogen in the baboon cohort.
• Specific numerical ranges for these coagulation parameters were established based on the analyzed samples.
• Age-related variations in coagulation parameters were considered in the data analysis.

Conclusions:

• The established reference ranges provide critical baseline data for baboon coagulation studies.
• These findings enhance the reliability of baboon models in preclinical research involving hemostasis.
• This study contributes essential hematological information for primate research and veterinary diagnostics.
