How much blood from an animal can be collected at one time?

BLOOD COLLECTION GUIDANCE**

The maximum volume of blood that can be collected may not exceed 1% of the body weight (or 10 ml/kg) in any animal in a two‐week period. For example: • No more than 0.3 ml (300 μl) can be collected from a 30 g mouse, over a two-week period.

Besides, What is the blood collection limit for animals?

All non-terminal blood collection without replacement fluids is limited to 10% of the total circulating blood volume of a healthy animal during a 2 week period. On average, the total circulating blood volume is equal to 5.5 -7.0 % (~66 ml/kg) of the animal’s body weight.

Keeping this in mind, How much blood can be collected from an animal in a single withdrawal expressed as percent of body weight )? 1. Acute (single withdrawal): A maximum of ~1% of the animal’s body weight in grams can be removed at one time with a minimum 2-week rest period without requiring supplemental fluids. Calculation Examples: 15 g mouse = 0.01 (1% body weight) x 15 g = 0.15 ml. 20 kg pig (20,000 g body weight) = 0.01 x 20,000 g = 200 mls.

How much blood can be drawn from a rabbit?

Total blood volume of a rabbit is 60 ml/kg or 6.0 % of total body weight (BW). No more than 1% of the animal’s blood volume in one collection or over a 24 hour period. No more than 7.5% (4.5 ml/ kg BW ) of total blood volume can be collected in a single or multiple draws over a week period.

How much blood can be taken from a mouse?

Under ideal conditions, a skilled person can obtain approximately 50-75% of a mouse’s total blood volume (3-4% of BW) by exsanguination. This amounts to 0.04-0.06 ml blood/gm BW, or 1.0-1.5 ml blood from a 25 gm mouse.

How much blood can be collected from a dog?

Total blood volume of a canine is 80 ml/kg or 8% of total body weight (BW). No more than 1% of the animal’s blood volume in one collection or over a 24 hour period. No more than 7.5% (6 ml/kg BW ) of total blood volume can be collected in a single or multiple draws over a week period.

What is the maximum percentage of total blood that can be safely collected at one time from a mouse?

In general, without fluid replacement, approximately 10% of the total blood volume (0.75% of BW) can be safely removed at one time; with fluid replacement, up to 15% (approximately 1.5% of BW) can be removed (Smith and Hamlin 1977; McGuill and Rowan 1989; Authement 1992; Waynforth and Flecknell 1992).

How much blood can you draw at once?

For an adult, the amount of blood that may be drawn for research purposes shall not exceed 5 ml/kg in any one 24 hour period, and 7 mL/kg in any eight week period. Any exception to these limits must be specifically justified in the research protocol and approved by a convened IRB.

How much blood can you take from a donor dog?

In dogs, approximately 400 to 450 mls (one pint/two cups) of blood is taken at each donation. Cats can donate 50 mls (1.7 ounces/3.33 tbsp) of blood.

How do you get a blood sample from a rabbit?

Extend the ear away from the rabbit’s head to provide a flat surface and insert the needle into the artery. Once blood begins to flow, lower the ear and position the receptacle under the needle for blood collection. Occasionally, the artery may constrict during the collection process, shutting off the flow of blood.

Where do you draw blood from a rabbit?

Rabbits are unique in having very accessible options on their ears for blood collection. You can use either the central artery or the marginal vein for a blood draw. You can also get a more than ample sample from the ear on your larger breeds, which is not the case with small breeds or young patients.

How much blood is taken for a blood test?

Although the volume of blood in a person’s body varies by weight and gender, most people have between 4,500 to 5,700 milliliters. Patients getting blood drawn for two routine testing panels — a complete blood count, or CBC, and a comprehensive metabolic panel, or CMP — can expect to lose maybe 10 milliliters.

What is the maximum volume of blood that can be taken from a mouse during survival blood collection?

Policy. The maximum amount of blood that can be drawn from a rodent in any 2-week period may not exceed 1% of the animal’s body weight. For example, for a mouse weighing 25 grams, the maximum allowable blood collection may not exceed 0.25 grams or 0.25 ml.

How do you get blood out of a mouse?

Terminal collection can be taken via cardiac puncture and can collect the maximum amount of blood. It can also be done via the aorta or vena cava. Immediately after the blood collection via either of these two methods—and before the mouse recovers from the anethesia—the mouse must be euthanized.
