How long does it take to be contacted if there is a problem with your donated blood?

It can take months, even years, if you receive any notification at all. The blood collectors have your privacy rights to be concerned with and, given the choice between creating a document that can be used against them in court (if it goes to the wrong home, for example) and doing nothing, they will choose to do nothing. When they receive blood from a non-acceptable source (such as your name being on the list of unqualified donors), they simply dispose of it to avoid problems and embarrassment.

What is rapid linear progression?

The term rapid linear progression is often used in conjunction with semen analysis. In most men, sperm cells (spermatozoa) should move rapidly (fast) in a linear (straight) fashion so as to reach the ovum and cause fertilisation. When lab technicians examine semen microscopically, as part of the investigation of sub-fertility in a couple, the technicians estimate the percentage of sperm cells that move rapidly and in a straight line. Other observations include the percentages include that of sperm moving rapidly but not in a linear (straight/progressive) fashion, those moving sluggishly and the percentage of immotile spermatozoa. Ideally, 25% of the spermatozoa should move with rapid linear motion (progression). The exact reference value however, depends on the individual lab and possibly population being served by that lab.

What are the dangers of having an rh neg fetus in an rh pos mother?

There are no dangers for the mother. Rh is a factor in blood, if you have the Rh factor you are Rh+. If not you are Rh-. If an Rh+ mother has an Rh- baby, there is nothing for her to react to, she has the factor. The baby doesn't.

If an Rh- mother carries an Rh+ baby, the mother's body may create antibodies that will cause her body to treat the baby as a foreign tissue. A woman who is Rh- seldom has problems in a first pregnancy, but later pregnancies the Rh antibodies can cause serious complications in the baby before birth and as a newborn. Rh- woman are given Rh immune-globulin shots, Rh immune-globulin acts like a vaccine, preventing the mother's body from producing any potentially dangerous.antibodies.

She must have the injection in the 72 hours following the birth for it to have an effect. Usually she will receive the first injection about half way through the pregnancy. A dose of Rh immune-globulin may also be given if a woman has a miscarriage, bleeding during pregnancy or some prenatal tests that could potentially allow the blood from the fetus to enter the mother's blood stream.

A baby that is Rh+ with an Rh- mother may be severely compromised in the womb and may need a transfusion during the pregnancy and again after birth. Fortunately Rh immune-globulin shots almost completely eliminate the risks.

If you take a loratab 7.5 will you be ok?

I reccommend using the CWE method to remove the acitiminophin from it but yes, you can dose codiene up to 30mg and be just fine (for a first time user). Good luck and happy hunting.

Can blood type B positive live kidney donor give to an O blood type patient?

Type O-negative blood does not have any antigens. It is called the "universal donor" type because it is compatible with any blood type. Type AB-positive blood is called the "universal recipient" type because a person who has it can receive blood of any type.

Although "universal donor" and "universal recipient" types may be used to classify blood in an emergency, blood type tests are always done to prevent transfusion reactions.

Yes, Adipex shows up as amphetamine usage. As far as just one I'm not really sure but I would think so.

Why are blood types a and b incompatible?

Blood types A and B are incompatible because a type A person has naturally occurring Anti-B in his blood and a type B person has naturally occurring Anti-A. Thus a type A person can not receive blood from a type B person because the naturally occurring anti-A would destroy the type A person's red cells. The converse is true for a type B person who can not receive type A blood since the Anti-B found in the type A blood would destroy the type B person's red cells.
