This is a type of solubility testing for sickle cell disease. It is very specific for this disease and several combinations sickle cell / thalassemia variants but inadequate for screening and fail to identify important transmissible hemoglobin gene abnormalities - particularly in the prenatal setting when looking for those that affect fetal outcome (eg, Hb C trait, β-thalassemia trait, Hb E trait, Hb B trait, Hb D trait).
Na+ is the medical and chemical symbol for the sodium ion.
Positive may be abbreviated "pos" or with a plus sign (+).
The abbreviation OP that is seen on bank statements stands for originator plus. The abbreviation OP is typically used to describe a direct debit payment.
To find what one half plus a certain value equals two thirds, you can set up the equation: ( \frac{1}{2} + x = \frac{2}{3} ). Subtracting ( \frac{1}{2} ) from both sides gives ( x = \frac{2}{3} - \frac{1}{2} ). Converting to a common denominator (which is 6) results in ( x = \frac{4}{6} - \frac{3}{6} = \frac{1}{6} ). Therefore, one half plus one sixth equals two thirds.
To add ( \frac{9}{12} ) and ( \frac{2}{4} ), first simplify ( \frac{2}{4} ) to ( \frac{1}{2} ) or ( \frac{6}{12} ) for a common denominator. Now, ( \frac{9}{12} + \frac{6}{12} = \frac{15}{12} ). This can be simplified to ( \frac{5}{4} ) or ( 1 \frac{1}{4} ).
To find the sum of (2 \frac{12}{23}) plus (4 \frac{23}{23}), first convert both mixed numbers to improper fractions. This gives us (\frac{58}{23} + \frac{92}{23} = \frac{150}{23}). Converting back to a mixed number, (\frac{150}{23}) equals (6 \frac{12}{23}). Thus, the final answer is (6 \frac{12}{23}).
In medical abbreviations, the plus sign ("+") is sometimes used to mean "and."
\frac{x}{7}
The expression ( \frac{a}{b} + \frac{c}{d} ) can be combined by finding a common denominator. The result is ( \frac{ad + bc}{bd} ). Thus, ( \frac{a}{b} + \frac{c}{d} = \frac{ad + bc}{bd} ).
To add ( \frac{2}{5} ) and ( \frac{2}{7} ), we first find a common denominator, which is 35. Converting the fractions, we have ( \frac{2}{5} = \frac{14}{35} ) and ( \frac{2}{7} = \frac{10}{35} ). Adding these gives ( \frac{14}{35} + \frac{10}{35} = \frac{24}{35} ). Therefore, ( \frac{2}{5} + \frac{2}{7} = \frac{24}{35} ).
To add ( \frac{8}{3} ) and ( -\frac{9}{4} ), first find a common denominator, which is 12. Rewrite the fractions: ( \frac{8}{3} = \frac{32}{12} ) and ( -\frac{9}{4} = -\frac{27}{12} ). Now add them: ( \frac{32}{12} - \frac{27}{12} = \frac{5}{12} ). Therefore, ( \frac{8}{3} + -\frac{9}{4} = \frac{5}{12} ).
It means positive or affirmative in medical abbreviations.
