What blood can type O safely receive?

Not taking Rh Factor into consideration, O is the universal donor. All blood types can receive type O. For information, AB is the universal recipient. They can take any blood type. Remember, this excludes the Rh Factor.

What does it mean when monocytes are slightly high?

An elevated monocyte count usually indicates an immune response in the body, potentially due to an infection or inflammation. It could also be a normal response to stress or certain medications. Further evaluation by a healthcare provider may be needed to determine the underlying cause.

What if mom and dad both 0 positive - and child b negative?

It is possible for a child to have a blood type that is different from either parent if both parents are carriers of a different blood type allele. In this case, the child could inherit the O negative blood type if both parents are carriers of the O negative allele.

What is the function of the mucous membrane of the human body?

The mucous membrane serves as a protective barrier in the body, lining various organs and cavities. It helps trap pathogens, preventing them from entering the body, and also helps lubricate and moisten surfaces for easier movement and function.

In the US about 45 percent of the population has blood type o about how many people out of every 100 have blood type o?

45% means 45/100, so about 45 people out of every one hundred people have O type blood. That is 9/20 in exact form.

Indications for taking blood cultures and appropriate site selection?

I. INDICATIONSRoutine blood cultures should be performed on any patient in whom there is a suspicion of bacteremia or candidemia.Isolator blood cultures should be performed on any patient suspected of having one of the following:1. Subacute or chronic endocarditis with multiple negative BACTEC system cultures. It is appropriate to use the BACTEC system for the initial workup of endocarditis of any suspected etiology. Isolators should be used after multiple BACTEC cultures are obtained and fail to reveal an etiologic agent (including HACEK).2. Suspected deep fungal infection, such as histoplasmosis, blastomycosis, and coccidioidomycosis. Ordinarily, cultures of other sites, such as tissue biopsy, and in some cases serological tests, are more helpful than blood culture.3. Suspected mycobacteremia, particularly in HIV patients with CD4 counts <50.4. Suspected disseminated gonococcal infection.5. Suspected bartonellosis.6. Suspected candidemia or disseminated cryptococcosis in patients for whom routine cultures have not detected Candida species or Cryptococcus neoformans, respectively.7. Suspected Malassezia furfurinfection, an agent of catheter-associated infection in patients receiving intravenous lipid.The indication for use of isolators should be given to the microbiology resident (pager #980-9869), who must approve the test.The following is not an indication for blood cultures of either type:Surveillance for infection before the clinical suspicion of infection exists.

Can a sample of blood from a piece of clothing be use for DNA testing?

Yes, a sample of blood from a piece of clothing can be used for DNA testing. The DNA extracted from the blood can be compared to known DNA samples to help identify a person or provide information about their biological relationships.

What is pus cells?

Pus cells are a type of white blood cell that are produced by the body to help fight off infections. They are often found in areas of the body that are infected or inflamed, and their presence can indicate an ongoing immune response.

Can chromosomes be seen only during cell division?

No, chromosomes can also be seen in non-dividing cells during interphase under a microscope. In interphase, chromosomes are less condensed and appear as long, thin, thread-like structures within the nucleus. During cell division, chromosomes condense further to become more visible as distinct structures.

What blood type would a child be with a AB neg mother and O positive father?

The child would most likely have either blood type A positive or B positive. A child inherits one blood type allele from each parent, so with an AB negative mother and an O positive father, the child could receive the A allele from the mother and the O allele from the father, resulting in blood type A positive. Alternatively, the child could receive the B allele from the mother and the O allele from the father, resulting in blood type B positive.

Why is the streak plate preferred over the spot inoculations in the blood agar test?

The streak plate method allows for isolation of individual colonies from a mixed culture, providing pure cultures for further analysis. This helps in identifying specific pathogens more accurately compared to spot inoculations, which may not allow for such isolation and can lead to difficulty in distinguishing different organism colonies on the plate.

What is neutrophils in hematology test?

Neutrophils are a type of white blood cell that plays a key role in the body's immune response. In a hematology test, the level of neutrophils in the blood is measured to assess the body's ability to fight off infections. Abnormal levels of neutrophils can indicate various health conditions, such as infections, inflammation, or bone marrow disorders.

Which blood groups are match with AB for marriage?

An individual with AB blood type can marry any other blood type, as AB is considered a universal recipient. However, for the possibility of future offspring compatibility, it is advised to consider potential blood type combinations and consult a healthcare provider for personalized advice.

The person who conducts lab tests on your blood is typically called a medical laboratory technician or a phlebotomist. They are trained to collect blood samples and analyze them to provide information about your health.

What happen to the male and female baby if both father and mother are o positive or one is negative and one is positive?

My son is 0- and my daughter in law is 0+ and they just had a A+ baby boy. It is very rare but the doctor said it can happen because every has a primary and secondary (recessive) blood gene. Since my d-i-law's father is A+ and her mother is 0+ and his parents are both 0+ but his mothers mother is A+ and her Father is 0+ there are many recessive A+ genes in their DNA blood type therefore they can have a A+ child. (Example mother is O+/A+ and father is 0-/A+ equals= A+/0 child.) 0 seems to be universal and can throw off a recessive gene. In our case; since it is rare; the baby and the mother's blood types caused him to have alot of jaundice (18) so he had to go back in hospital to be under the light for an additional 24 hours to bring it down. She was nursing and her milk had not come in to give him the fluids to fight off the excess billiruben count. Other than that; it will not be a problem for either of them.

As it is hard to find this information on the Internet. Most sights say no because they are stating the normal without considering the recessive secondary gene type that are rare. Ask a doctor .....it happens

What does it mean to have too much protein in your blood?

Having too much protein in your blood, known as hyperproteinemia, can indicate various underlying health conditions such as dehydration, infections, inflammatory disorders, or multiple myeloma.

You and your siblings can only get a negative allele from your mom because her two are negative.

What does a low MPV in hematology testing mean?

MPV is mean platelet volume. The average normal range for MPV is a blood test is around 7.5-10.5 fl.

A low MPV can mean many things. In a female during her reproductive years her MPV will be low for the first few days of menses [her period]. Platelet count is high in a woman after delivering a child and newborns have naturally low levels.

Basically all it means is you have a low platelet count. This in turn puts you at a risk for bruising and bleeding.

The causes of low MVP are varied and not always known. Low levels can be caused by viral infections, especially AIDS; Genetic disorders like Lupus; Hemolytic disorders, like Anemia; an overactive spleen, and taking drugs that low your count; like heparin.

So, if your doctor mentions this, it's time to have a little chat about what's going on in your bones.

What are normal levels of WBC in urinalysis?

Normal levels of white blood cells (WBCs) in a urinalysis are typically less than 5 WBCs per high power field (HPF) in a clean catch urine sample. Elevated levels of WBCs in the urine may indicate infection, inflammation, or other underlying health conditions.

What does RBC means in a hematology test?
