Yes. The explanation is similar to that for a type O child of type A parents (see answer to previous question). In this case, the Rh type depends on a gene called 'D'. The absence of D results in a gene called 'd'. In your family, the genes of both you and your wife must be Dd. Your son must have inherited the d gene from each of you in order to be type Rh negative.

Yes. A person's blood type results from inheriting a gene for A, B or O from each parent. Two genes result, and this determines the blood type of the child. Type O is the name given when someone lacks an A or B gene. When O is present along with the gene for A or B, e.g. AO or BO, the A or B is the dominant gene and determines that person's type, as shown below: In your family, the genes of both you and your wife must be AO.

PLATELETS: ABO and Rh compatible platelets will be released for transfusion. If this is not feasible because of limited inventory and /or emergent need for the component, ABO and /or Rh incompatible platelets may be issued. It may be advisable to administer Rho (D) immune globulin to selected Rh-negative patients who receive platelets from Rh-positive donors, since sensitization to red cell antigens may occur from the few red cells present in platelets.

Unfortunately, yes. Although false negatives are not very common, they do occur, because no test is 100% accurate all of the time. Unlike FIV, FeLV tests test for antigens, not antibodies, so maternal antibodies are not an interfering problem and kittens can be tested at any age. To be absolutely sure a cat is not FeLV+ you should test it twice, a few weeks apart (the cat should remain isolated from other cats during this period; too, otherwise there is little point in doing a second test).

There are four major blood groups---O, A, B, and AB-each of which is divided into Rh positive or negative types. A patient's blood and the donor blood being transfused should be compatible, both in regard to major ABO group and Rh type. Of each 100 individuals, on the average, 45% will be group O (39% Rh positive, 6% Rh negative) ...40% will be group A (35% Rh positive, 5% Rh negative)...10% will be group B (8% Rh positive, 2% Rh negative)..

A - The Rh+ or Rh- does not play into the blood type diet. This is another blood typing system referred to as the Rhesus factor. The name originated from the rhesus monkey that is used in numerous laboratory studies. Its significance is primarily in the case of pregnancies or organ transplants. See similar questions...

False negative results are more common than false positives - and are primarily due to inaccuracies in timing of the test or carelessness in the test procedure itself. Please follow test instructions with circumspection and precision. A false negative result can also stem from using a diluted urine sample and/or from taking a test too early in pregnancy. First morning urine contains the most concentrated presence of hCG - which makes it the ideal sample for pregnancy testing. See similar questions...

With Autosomal Dominant PKD, the only form of PKD so far identified and confirmed in cats, two genetic negative parents cannot produce a genetically positive offspring unless that offspring is a fresh mutation. See the discussion on autosomal-dominant inheritance below for further details. See similar questions...

The potential risks are significant, and include but are not limited to death, extreme shock, convulsions, dizziness, pain, bleeding, loss of consciousness, nausea, vomiting, scarring, and numbness. See similar questions...

Yes. Use the =SUMIF function to do so. To add only negative numbers, use =SUMIF(range,<0) To add only positive numbers, use =SUMIF(range>0) See similar questions...

Yes, if there is some ingredient which the drug test reacts to. A laboratory method will then look for the specific substance that caused the test to show positive. See similar questions...

Answer: A blood test performed in our lab will determine your RH factor. If your blood is RH negative, you will be given an injection of MicroRhoGAM following the procedure. See similar questions...

Do not attempt to interpret results after the five minute test reaction time. Depending on the concentration of hCG in the test specimen, positive results may be observed in as little as 40 seconds. However, to confirm negative results, the complete reaction time of 5 minutes is required. A positive result can only be determined within this time interval. See similar questions...

Being negative can be very positive. There is a difference between being nihilistic and being negative in the sense of being cautious and critical before believing a claim or accepting an explanation for something. A nihilist denies the value of everything. Many religious people are nihilists since they deny the value of anything in this world. The leaders of religions often reject family, reproduction, the joys of the body, the pleasures of art and nature. See similar questions...

Yes. Such results can be caused by technical problems with the biopsy equipment; not getting the correct sample; the method of biopsy done was not suitable for the lesion(s) present. See similar questions...

Yes a blood-test will show positive because of the antibodies. a P.C.R. test will confirm if the virus is gone because after 10 treatments or more there should be NO viral DNA left.

Lola, Utah, USA: Yes, some elevated hCG levels can be due to other factors besides GTD or recurrent trophoblastic disease. Certain hormone fluctuations and proteins in the blood may interfere with blood test results. Both tests should be requested, especially in initial diagnosis of GTD, as well as diagnostic testing for suspected GTD, before any invasive treatment recommendations are pursued. Lola, Utah, USA: GTD is diagnosed and followed by measuring hCG hormone in the blood and urine. See similar questions...
