A computer crossmatch requires that an ABO phenotype be performed on the current specimen and a second phenotype must be performed or available for confirmation of the blood type. The recipient must be negative for clinically significant antibodies both with current sample and historically.
True / False.

True

Explanation:

A computer cross match checks the compatibility of the final ABO in selecting units instead of serologic procedures.

The recipient must not have antibodies or history of it.

Barcodes are used in providing other safety measures. The computer provides the signal to show if the recipient is eligible or not for a computer cross match.

A computer cross match is a computerised way of analysing the compatibility of a donor's cell type with that of the serum or plasma type of the person receiving it. This process is aimed at ensuring that blood sample used for transfusion is compatible with that of the person meant to receive it.

True.

Explanation:

Crossmatch or compatibility testing is basically performed to check the compatibility of donor blood (RBCs) to the recipient to prevent the transfusion reaction and to maximize the in-vivo survival of transfused RBCs.

Computer cross match is to counter check the donor blood sample phenotype and recipient phenotype along with any previous transfusion history with antibodies (recipient must not have antibodies against the phenotype of donor blood).

Another feature of computer crossmatch is bar coding. Bar codes detects the recipients eligibility or ineligibility for computer crossmatch by tagging or flag.

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
