2023
Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Central venous access is necessary in a multitude of clinical situations, including vascular access, vasopressor and caustic medication delivery, central venous pressure monitoring, volume resuscitation, total parental nutrition, hemodialysis, and frequent phlebotomy. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the...

2025
Here, we present a protocol for an optimized blood collection technique in murine subjects through facial vein venipuncture using a lancet. We use this technique alongside flow cytometric assessment to characterize cellular phenotypes of transgenic, congenic, and reporter strains. It is also suitable for serum cytokine analysis and diabetes studies.

This protocol describes a procedure for serial sampling of femoral bone marrow (BM) without requiring the sacrifice of mice. This procedure facilitates longitudinal studies of the BM composition of mice over time and provides serial access to cells within the BM for ex vivo and transplantation studies.
FAQs
Selection is mainly driven by access and volume requirements. The femoral vein provides an alternative when peripheral access is limited, and its use can support collection of larger sample volumes. This makes the method useful when a study needs enough blood for hematology, biochemical analysis, or pharmacokinetic measurements without changing the analytical goal.
Restraint, site preparation, and aseptic handling control different risks in the same workflow. Appropriate restraint helps maintain access to the thigh during puncture, while preparation and asepsis help protect the collection site and preserve sample integrity. Together, these conditions make the sampling event more controlled and reduce avoidable complications.
Gentle negative pressure is important because blood must be drawn into the syringe or tube without making collection unnecessarily forceful. The pressure applied after needle or catheter removal serves a different purpose: it helps control bleeding. Separating collection pressure from post-collection pressure supports both usable samples and safer handling.
The key distinction is the access site and the reason for choosing it. Femoral Vein Collection targets a large vessel in the thigh, whereas peripheral access may be inadequate for the required collection. Consequently, the femoral approach can be selected when access is limited or when a larger sample volume is needed.
A needle or catheter provides entry into the vein, while the syringe or collection tube receives blood drawn by gentle negative pressure. This separation between vascular access and sample collection allows the operator to use the collection format suited to the study. Consistent handling is especially relevant when samples undergo hematology, biochemical, or pharmacokinetic analysis.
Femoral vein collection supports several biology and biomedical research applications. Samples can be used for hematology, biochemical analysis, pharmacokinetic studies, and longitudinal blood sampling. The method therefore connects a single collection event with both laboratory measurements and studies that track changes across time.
Its value in longitudinal work comes from enabling blood sampling at multiple study time points when peripheral access is limited or the protocol requires more blood. Researchers can then use successive samples for hematology, biochemical analysis, or pharmacokinetic measurements, helping relate laboratory findings to change over the course of a study.
