Calcium falsely high due to elevated albumin ?

I'm 23, male. My endocrinologist told me I don't have primary hyperparathyroidism but rather I have secondary hyperparathyroidism because my calcium is falsely elevated in the blood reports due to elevated albumin.

What do you think ?

serum ca = 10.48 mg/dl (8.10 - 10.40)   (10/10/12)
pth = 61.20 (15 - 68)                             (10/10/12)
albumin = 4.67 g/dl (3.5 - 5.5)                (10/10/12)
*CORRECTED SERUM CALCIUM* = 9.94 mg/dl

serum ca = 10.58   (8.10 - 10.40)           (8/11/12)
albumin = 4.96 g/dl (3.50- 5)                  (8/11/12)
*CORRECTED SERUM CALCIUM* = 9.81 mg/dl

Other reports

ca = 11 ;  (26/9/12)  
pth = 150 ; ca = 12   (27/9/12) (This could me high due to 2 vitamin d supplements I took with added calcium citrate)
pth = 103.80 (15 - 68); ca = 10.02  (8.10 - 10.40)  (3/10/12)
pth = 51.40 (15 - 68); ca = 10.30   (8.10 - 10.40)   (18/10/12)
pth = 36.20 ; ca = 10.60       (31/10/12)
phosphorus = 3.5 (2.5 - 5.0) (26/9/12)
phosphorus = 5.00   (2.70 - 4.50)  (10/10/12)
phosphorus = 4.89 mg/DL (2.70 - 4.50) (2/11/12)

vitamin d = 3.42 ng/ml ( > 30 ng/ml)  (26/9/12)
vitamin d = 28.80 nmol/L (>-=75 -250)  (16/10/12)
vitamin d = 32.80 nmol (>= 75  -250 )    (31/10/12)

Alkaline phosphate = 353 u/L  (108 - 306) 27/9/12
Alkaline phosphate = 106 u/L  (30 - 120) 20/10/12

creatinine, serum 0.61 mg/DL (0.77 - 1.42)     (2/11/12)
creatinine, serum 0.73 mg/DL (0.77 - 1.42)     (5/11/12)

magnesium  = 1.8 mgm/dl (1.70 - 2.70) (27/9/12)
magnesium = 2.00 mg/DL (1.80 - 2.60) (16/10/12)
magnesium = 1.70 mg/DL (1.80 - 2.60)    (30/10/12)

New report shows normal pth and a normal calcium level.

Pth = 38.8 (15 - 68) , ca =  9.8 (8.8 - 10.6); ionized ca = 1.21 (1.16 - 1.32) (19/11/12)
albumin = 5.04 g/dl (3.5 - 5)   (19/11/12)
phosphorus = 5.07 (2.7 - 4.50)  (19/11/12)

Ca = 9.99 (8.10 - 10.40)      (20/11/12)
Ca = 10.30 (8.10 - 10.40)    (22/11/12)

These calcium levels are consistently high, accompanied by high or high normal PTH levels.  Your phosphorus has been high or normal, which is not typical with primary hyperparathyroidism.  The vitamin D level looks normal.  Alkaline phosphatase levels have been high or normal.  This is suspicious for primary hyperparathyroidism but as a young adult, calcium levels can normally run in the mid 10 range.  Therefore a second opinion from an endocrinologist may be warranted.
