Common blood disorders include anemia, bleeding disorders such as hemophilia, blood clots, and blood cancers such as leukemia, lymphoma, and myeloma.

Suggested primary analysis

Purpose

Tail-vein clotting test in warm saline indirectly examines the volume of blood loss before spontaneous staunching. Proposed first-line analysis for potential clotting disorders with second-line analysis by ex vivo coagulation testing.

Purpose

The measurement of various blood metabolites, ions, and enzymes provides a primary screen for  function of major metabolic organs such as kidney, liver, gastrointestinal tract, as well as for lipid and glucose homeostasis. 

A panel of parameters is proposed, including:

  • Electrolytes and ions: Sodium (Na), Potassium (K), Chloride (Cl), Calcium (Ca), Magnesium (Mg), Phosphate (PO4), iron (Fe), and bicarbonate (CO2).
  • Enzymatic activities: Alpha-amylase, aspartate amino transaminase (AST), alanine amino transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), lipase, creatine kinase (CK).
  • Metabolites: glucose, urea, creatinine, uric acid, total proteins, albumin, total bilirubin, triglycerides, free fatty acids, glycerol, total, HDL and LDL cholesterol, fructosamine, ketone bodies (B-HBA), transferrin, ferritin.

Selected plasma chemistry data from female mice (N=20 per line) of common laboratory strains at different ages (Champy et al. Mammalian Genome 2008).  Error bars reflect ± SEM.

Equipment

These tests are performed with an AU-480 automated laboratory work station (Beckman Coulter France SAS, Villepinte, France).

Purpose

Determination of prothrombine time, activated partial thromboplastin time and fibrinogen activity.

Recommendations

It is recommended to collect blood by intra-cardiac puncture.

Suggested secondary analysis

Purpose

First-line hematological/immunological analysis of blood or tissue infiltrates for different leukocyte lineages. May be targeted to examine particular immune lineage subclasses.

Exemples:

Thymus: 

  • T cells of ab lineage: CD4/CD8/TCRab 
  • T cells of gd lineage: CD4/CD8/TCRgd 
  • NKT cells: NK1.1/CD3 

Spleen: 

  • B cells: CD19/IgM/IgD/CD80 
  • B cells: CD19/IgM/CD2/CD23 
  • NK cells and NKT cells: DX5/NK1.1/CD3 
  • Macrophages and neutrophils: F4-80/Gr-1/Mac-1 
  • T cells: CD4/CD8/CD3/CD44

Blood:

  • B cell: CD19/mature B cells IgD
  • Granulocyte
  • Monocyte
  • NK cell 
  • T cell : CD3/CD4/CD8
  • Treg cell : CD25
