There are two medical terms for this process. Registration - the linking of a metal IV syringe to a vein the same way a small tube would pierce and connect to a larger sized tube. Extraction - the suction process using air pressure to remove blood and store it for testing and later use.

For best results:

* Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest * Don't drink a bunch of fluids before taking the test because it will dilute your urine and can affect the results * Take the test no more than 1-2 days before expected period. Although some test say that you can see results up to 5 days before your missed period the percentage of accuracy is very low. * urinate for as long as possible on the foam like strip * wait for the results

If a loved one was in need of blood or they would die wouldn't you want them to be able to get that blood? If you give blood you can make another family grateful. and you may just save someone's life

Yes, certain organs, e.g., one of a person's two kidneys, or part of the liver, can be transplanted from a living donor.

High Hematocrit means that the person is unhealthy and suffering from any one of a number of medical conditions.

It also means that the blood is more viscous than is required and can cause damage to the heart.

If taken for hypertension, and BP is within acceptable limits, then potential donors taking Ramipril are eligible for volunteer blood donation. If taken for heart failure or with a history of cardiac ischemia w/wo myocardial infarction, then the donor would be deferred. Please contact the medical director of your local blood collection facility and review your case.

If you meant "is it possible to exchange all the blood with any substitute?" - then "no. that's impossible".

But probably you didn't mean that - would be crazy.

If your looking for some substance to substitute blood during a surgery, i.e. to avoid blood transfusion (as it is always a risky thing)... then yes. High tech hospitals are already doing surgeries without real blood. The problem is the quantity that can be substituted by the specific substances... density, osmolarity... (they check those properties).

So... please check some medical information sites or whatever... I know it exists for sure... those hospitals are really modern (and maybe very few). But don't let anyone tell you there wouldn't be any at all... there has been an international special medical convention in Geneva (Switzerland) about surgeries without blood and blood substitutes. Good luck.

Answer: Some of the Methods

Fluids: Ringer's lactate solution, dextran, hydroxyethyl starch, and others are used to maintain blood volume, preventing hypovolemic shock. Some fluids now being tested can transport oxygen.

Drugs: Genetically engineered proteins can stimulate the production of red blood cells (erythropoietin), blood platelets (interleukin-11), and various white blood cells (GM-CSF, G-CSF). Other medications greatly reduce blood loss during surgery (aprotinin, antifibrinolytics) or help to reduce acute bleeding (desmopressin).

Biological hemostats: Collagen and cellulose woven pads are used to stop bleeding by direct application. Fibrin glues and sealants can plug puncture wounds or cover large areas of bleeding tissue.

Blood salvage: Salvaging machines recover blood that is lost during surgery or trauma. The blood is cleansed and can be returned to the patient in a closed circuit. In extreme cases, liters of blood can be recovered using such a system.

Surgical tools: Some devices cut and seal blood vessels simultaneously. Other devices can seal bleeding on large areas of tissue. Laparoscopic and minimally invasive instruments allow surgeries to be performed without the blood loss associated with large incisions.

Surgical techniques: Thorough operative planning, including consultation with experienced clinicians, helps the surgical team to avoid complications. Prompt action to stop bleeding is essential. Delays greater than 24 hours can greatly increase patient mortality. Dividing large surgeries into several smaller ones decreases total blood loss.

You can find much information on Jehovah's Witnesses official website. Working with Jehovah's Witnesses, many hospitals all over the country have developed a Bloodless Medicine Program and Department. Englewood Hospital snd Medical Center, Englewood, New Jersey is the frontrunner.

When a person donates blood, many tests are run on that blood, B12 is not one of those, so yes, a person with a B12 deficiency may be able to donate. However, It would not be advisable to do so as it may exacerbate some symptoms this person may have such as tiredness and fatigue.

they ask people to donate blood so that they can give the blood to people who need it because they have lost alot of blood and or going to have a transplant or oporation.

Potential donors with a history of PCV are permanently deferred from volunteer blood donation. PCV patients may, however, donate blood for their own use (autologous donation).

Yes

Yes. While occasional whole blood donations will generally have little effect on iron levels and body stores, frequent donations may decrease these amounts. Recently, the FDA has discussed the possibility of raising the the minimum hemoglobin or hematocrit levels for volunteer blood donation, or increasing the time allowed between donations, in response to lowered donor iron. Current guidelines require a pre-donation hematocrit of 38% or hemoglobin level of 12.5 g/dL. Whole blood donations may be given every 56 days, while double red cell donations require a 112 day deferral.

Therapeutic phlebotomy is very effective in preventing iron toxicity in hemochromatosis patients and decreasing red cell mass in red cell hyperplasia/polycythemia vera patients.

There are various issues you can encounter in donating blood. First, the equipment are not 100% safe. The needle, the storage bag and other materials should be sterile. Second, the place of donation is dirty. It should also be clean and neat - there should be no defects in donating chairs.

Blood is purified when it enters a nephron through the artiole, impurities are filtered out and emptied into the collecting duct. The purified blood exits the nephron through the venule.

Hope it helps ;)

No you can't donate plasma if you have had acupuncture.I was going to donate today and after 45 minutes of intake, I was asked if I ever had acupuncture and I said yes. I was then told I couldn't donate and I could come back in a year if I quit the acupuncture.

It's not a good idea. Lupus patients tend to have low white counts, low platelets, and suffer from anemia. Taking blood out makes this worse. If you are on chemo or biologics they won't want your blood anyway.

Because you don't want to give someone bad blood. This is the same for every disease.

FDA guidelines require a temporary deferral of one year from date of transfusion for potential donors who have received blood products. This is to minimize the possibility of transfusion-transmitted diseases entering the blood supply. Though unlikely, there is a risk of transfusion-acquired infections with all blood component use. The one year deferral allows any potential disease to be present long enough to be detected by FDA-mandated screening tests.

No... Im on medication for depression and Im not alowed... It depends though

You can still donate blood if you're on an antidepressant.
