The serum prolactin level is less sensitive for detecting partial seizures.

A fasting serum insulin level of greater than the upper limit of normal for the assay used ( approximately 60 pmol / L ) is considered evidence of insulin resistance.

The trend of serum creatinine levels over time is more important than absolute creatinine level.

Hyponatremia is defined as a serum level of less than 135 mEq / L and is considered severe when the serum level is below 125 mEq / L.

The presence and severity of symptoms are associated with the level of serum sodium, with the lowest levels of serum sodium associated with the more prominent and serious symptoms.

In the setting of hypovolemia, intravenous administration of normal saline may be effective, but caution must be exercised not to raise the serum sodium level too quickly ( see below ).

A hospital incidence of 15 – 20 % is common, while only 3 – 5 % of patients who are hospitalized have a serum sodium level of less than 130 mEq / L.

The serum prolactin level usually rises following an epileptic seizure.

Proteins may be administered intravenously to raise the level of serum proteins.

The screening blood test should typically include full blood count, liver function tests, thyroid function tests, lipid profile, erythrocyte sedimentation rate, C reactive protein, syphilis serology, calcium serum level, fasting glucose, urea and electrolytes, vitamin B-12, folate.

According to some guidelines, all people with RLS should have their serum ferritin level tested.

Giving 2 mg oral lorazepam will result in a peak total serum level of around 20 ng / ml around two hours later, half of which is lorazepam, half its inactive metabolite, lorazepam-glucuronide.

A similar lorazepam dose given intravenously will result in an earlier and higher peak serum level, with a higher relative proportion of unmetabolised ( active ) lorazepam.

( A serum creatinine level, a simple blood test, is needed to use the calculator ).

To convert from whole-blood glucose, multiplication by 1. 15 has been shown to generally give the serum / plasma level.

The initial test performed is serum A1AT level.

* PiMS: 80 % of normal serum level of A1AT

* PiSS: 60 % of normal serum level of A1AT

* PiMZ: 60 % of normal serum level of A1AT

* PiSZ: 40 % of normal serum level of A1AT

In the blood, about half of all calcium is bound to proteins such as serum albumin, but it is the unbound, or ionized, calcium that the body regulates.

It detects antibodies against RBCs that are present unbound in the patient's serum.

As an example, the important blood serum protein albumin contains 585 amino acid residues.

Modafinil and / or its major metabolite, modafinilic acid, may be quantified in plasma, serum or urine to monitor dosage in those receiving the drug therapeutically, to confirm a diagnosis of poisoning in hospitalized patients or to assist in the forensic investigation of a vehicular traffic violation.

* Trichloroacetic acid, chemical used to precipitate protein in serum

One of the last of those studies affirmed the superiority of inositol and xantinol esters of nicotinic acid for reducing serum free fatty acid, but other studies conducted during the same period found no benefit.

The drug is also used in people with gout or hyperuricemia ( high serum uric acid levels ).

Hyperuricemia is not necessary for the formation of uric acid stones ; hyperuricosuria can occur in the presence of normal or even low serum uric acid.

Repeated attacks can be prevented by different drugs used to reduce the serum uric acid levels.

Urate-lowering measures should be increased until serum uric acid levels are below 300 – 360 µmol / l ( 5. 0-6. 0 mg / dl ), and are continued indefinitely.

Rates are high among the peoples of the Pacific Islands and the Māori of New Zealand, but rare in Australian aborigines, despite a higher mean concentration of serum uric acid in the latter group.

# Other fibers, e. g., gum arabic, are associated with a significant decrease in serum cholesterol without increasing fecal bile acid excretion.

* Elevated serum levels of uric acid ( also responsible for gout )

It may somehow result in a reduction in the amount of lactic acid produced by the muscles, though serum lactate is typically slightly elevated with MADD.

Oxalic acid is found in chocolate, peanuts, certain types of berries, and other foods, and when combined with calcium will form calcium oxalate crystal kidney stones that can drive up blood pressure like any other serum salt, block urinary flow within the kidneys, and cause physical kidney damage and pain.

In their clinical decision analysis, they presumed initially a distress ratio of 10 ( defined as being the expected distress of severe complications valued as 10 times worse than the expected distress of a caesarean section ), and under these assumptions, they concluded that there would be the least expected distress from using serum uric acid for clinical decision making.

In people receiving hemodialysis, sevelamer can significantly reduce serum uric acid, apparently by adsorbing urate in the gut.

In women, use of combined oral contraceptive pills is significantly associated with lower serum uric acid.

Blood and urine tests for methylmalonic acid may indicate a B < sub > 12 </ sub > deficiency, even though serum B < sub > 12 </ sub > is within the normally acceptable range.

Results of the only reported randomized clinical trial in 1996 found that guaifenesin had no significant effects on pain, other symptoms, or laboratory measures ( serum and urinary levels of uric acid and phosphate ) over 12 months in a sample of people diagnosed with fibromyalgia syndrome, The lead author of the study has suggested a number of reasons why some patients may have previously reported benefits on this protocol, concluding " St. Amand has unknowingly used guaifenesin as a powerful focus in a program of cognitive behavioral therapy, in which his empathy, enthusiasm and charisma were the real instruments in effecting a beneficial change.

Monitoring of potassium and uric acid serum levels is recommended, especially in subjects with a predisposition or a sensitivity to hypokalemia and in patients with gout.

Simultaneously serum levels of patients with leukoplakia were found to be low in Vit A, B-12, C & folic acid, in a study conducted in India.

The serum uric acid concentration is often normal, as the excess purines are promptly eliminated in the urine.

Hyperuricemia ( serum uric acid concentration of > 8 mg / dL ) is often present but not reliable enough for diagnosis.
