Animal body parts where blood sample can be collected ?

1. Veins: Blood samples are commonly collected from veins in the arms, hands, or legs using a needle and syringe or a vacutainer.

2. Arteries: Blood samples can also be collected from arteries, such as the radial artery in the wrist or the femoral artery in the groin, for certain tests.

3. Capillaries: Blood samples can be collected from capillaries in the fingertips or earlobes using a lancet or fingerstick device.

4. Heart: In some cases, blood samples may be collected directly from the heart during a surgical procedure or cardiac catheterization.

5. Umbilical cord: Blood samples can be collected from the umbilical cord of newborn babies shortly after birth for testing.

6. Spleen: In rare cases, blood samples may be collected from the spleen during a surgical procedure.

7. Bone marrow: Blood samples can be collected from the bone marrow, usually from the hip bone, for certain tests or procedures.

8. Lymph nodes: Blood samples can be collected from lymph nodes in certain medical procedures or tests.

External Body Parts:

- Earlobe (pinna): Commonly used in small animals and infants.
- Tail: Can be used in larger animals such as cattle and horses.

Internal Body Parts (requiring minor procedures):

Venous:

- Jugular vein: Large vein in the neck, accessible in most animals.
- Cephalic vein: Located on the inside of the foreleg, commonly used in dogs and cats.
- Median cubital vein: Located in the elbow crease, used in humans and some animals.
- Saphenous vein: Located on the inside of the hindleg, near the knee.

Arterial:

- Femoral artery: Large artery in the hindleg, used for blood pressure measurements.
- Radial artery: Located on the wrist, used in humans.

Other Methods:

- Skin puncture (fingerstick): Used in humans and small animals, requires a specialized device (lancet).
- Capillary tube: Can be used to collect blood from small wounds or incisions.
