Typically, PTH levels vary greatly over time in the affected patient and (as with Ca and Ca++ levels) must be retested several times to see the pattern. The currently accepted test for PTH is intact PTH, which detects only relatively intact and biologically active PTH molecules. Older tests often detected other, inactive fragments. Even intact PTH may be inaccurate in patients with kidney dysfunction. Intact pth blood tests may be falsely low if biotin has been ingested in the previous few days prior to the blood test. Calcium levels
In cases of primary hyperparathyroidism or tertiary hyperparathyroidism, heightened PTH leads to increased serum calcium (hypercalcemia) due to:
increased bone resorption, allowing the flow of calcium from bone to blood
reduced kidney clearance of calcium
increased intestinal calcium absorption

Serum phosphate
In primary hyperparathyroidism, serum phosphate levels are abnormally low as a result of decreased reabsorption of phosphate in the kidney tubules. However, this is only present in about 50% of cases. This contrasts with secondary hyperparathyroidism, in which serum phosphate levels are generally elevated because of kidney disease. Alkaline phosphatase
Alkaline phosphatase levels are usually elevated in hyperparathyroidism. In primary hyperparathyroidism, levels may remain within the normal range, but this is inappropriately normal given the increased levels of plasma calcium. Nuclear medicine
A technetium sestamibi scan is a procedure in nuclear medicine that identifies hyperparathyroidism (or parathyroid adenoma). It is used by surgeons to locate ectopic parathyroid adenomas, most commonly found in the anterior mediastinum. Classification
Primary
Primary hyperparathyroidism results from a hyperfunction of the parathyroid glands themselves.
Amoxicillin/clavulanic acid, also known as co-amoxiclav or amox-clav, sold under the brand name Augmentin, among others, is an antibiotic medication used for the treatment of a number of bacterial infections. It is a combination consisting of amoxicillin, a β-lactam antibiotic, and potassium clavulanate, a β-lactamase inhibitor. It is specifically used for otitis media, streptococcal pharyngitis, pneumonia, cellulitis, urinary tract infections, and animal bites. It is taken by mouth or by injection into a vein.Common side effects include diarrhea, vomiting, and allergic reactions. It also increases the risk of yeast infections, headaches, and blood clotting problems. It is not recommended in people with a history of a penicillin allergy. It is relatively safe for use during pregnancy.Amoxicillin/clavulanic acid was approved for medical use in the United States in 1984. It is on the World Health Organizations List of Essential Medicines. The World Health Organization classifies amoxicillin/clavulanic-acid as critically important for human medicine. It is available as a generic medication. In 2019, it was the 93rd most commonly prescribed medication in the United States, with more than 8 million prescriptions. Medical uses
Amoxicillin/clavulanic acid is widely used to treat or prevent many infections caused by susceptible bacteria, such as:

urinary tract infections
respiratory tract infections
skin and soft tissue infections
sinus infections
tonsillitis
cat scratches
infections caused by the bacterial flora of the mouth, such as:
dental infections
infected animal bites
infected human bites (including uncomplicated "clenched-fist" or "reverse-bite" injuries)It is also used for tuberculosis that is resistant to other treatments.
