csf albumin csf albumin csf albumin is a measurement used to determine the levels of albumin in cerebrospinal fluid. csf albuminloinc1746-7 (mcnc)2861-3 (mcnc, electrophoresis)43711-1 (acnc) a closely related test, csf total protein is a measurement used to determine the levels of protein in cerebrospinal fluid. it combines the albumin, igg, and other proteins. it can be useful in distinguishing among causes of meningitis. it is more likely to be elevated in bacterial meningitis than in viral meningitis. the upper normal range is 150 mg/dl in neonates, and 50 mg/dl in adults. pathophysiology sample values bmp/electrolytes: na+ = 140 cl− = 100 bun = 20 /glu = 150\ k+ = 4 co2 = 22 pcr = 1.0 arterial blood gas: hco3− = 24 paco2 = 40 pao2 = 95 ph = 7.40 alveolar gas: paco2 = 36 pao2 = 105 a-a g = 10 other: ca = 9.5 mg2+ = 2.0 po4 = 1 ck = 55 be = −0.36 ag = 16 serum osmolarity/renal: pmo = 300 pco = 295 pog = 5 bun:cr = 20 urinalysis: una+ = 80 ucl− = 100 uag = 5 fena = 0.95 uk+ = 25 usg = 1.01 ucr = 60 uo = 800 protein/gi/liver function tests: ldh = 100 tp = 7.6 ast = 25 tbil = 0.7 alp = 71 alb = 4.0 alt = 40 bc = 0.5 ast/alt = 0.6 bu = 0.2 af alb = 3.0 saag = 1.0 sog = 60 csf: csf alb = 30 csf glu = 60 csf/s alb = 7.5 csf/s glu = 0.6
