How do we calculate corrected se Ca+

If Se Calcium is 13 meq/l n Albumin 2.5 then whats the corrected se ca?shaking head

  #2

anyone??nod

  #3

Ca correction:0.8 (normal album. -pte. album.)+ serum Ca

= 0.8(4-2.5)+13=

= 14.2


  #4

Ca correction:0.8 (normal album. -pte. album.)+ serum Ca

= 0.8(4-2.5)+13=

= 14.2


  #5

Yes , Washington manual says

Corrected Ca = Ca + .8 x 4-albnod

pass grin

  #8

i guess sr calcium ( corrected ) is expected ..... so if pateints sr calcium is 13 and we calculate with above formula corrected calcium 14.2

so we are short of 1.2 units of calcium so give that much to get to corrected level ....

this is wat i think.......correct me if i m wrong




  #9

confused
This case said that Ca is 13 with low albumin that means this pte has hypercalcemia.
When we correct the albumin Ca. value, it supposts to increase more... are we going to give more calcium????
