Spurious sodium results (1) – pseudohyponatremia
Disturbance of sodium balance is a common occurrence among hospitalized patients that can, if not identified and treated, cause significant morbidity; severe disturbance is potentially lethal. So estimation of plasma sodium concentration is one of the most frequently requested blood tests.
Historically, plasma sodium ...

Estimating glomerular filtration rate
Glomerular filtration rate (GFR) is a parameter of prime clinical significance because it defines kidney function. All those with reduced kidney function, no matter what the cause, have reduced GFR, and GFR correlates well with disease severity. The most accurate assessment of GFR is thus valuable not only for early...

Umbilical-cord blood gas analysis
The pH, base excess and pCO2 (acid-base status) of arterial blood flowing through the umbilical cord provides valuable objective evidence of the metabolic condition of neonates at the moment of birth; a notion that has assured a role for the blood gas analyzer in hospital delivery suites in cases of suspected fetal...

The value of point-of-care testing in deteriorating ward patients
Point-of-care testing (POCT) for key laboratory variables may help clinicians assess the level of acuteness and the level of care necessary in the management of deteriorating ward patients.
We used a multibiomarker POCT panel including B-type natriuretic peptide (BNP), D-dimer, myoglobin (Myo), creatine kinase MB...

How to use high-sensitivity cardiac troponin assays most effectively in clinical practice
Recently developed high-sensitivity cardiac troponin (cTn) assays can measure approximately 10 times lower concentrations with high precision (coefficient of variation, <10 % at the 99th percentile of the upper reference limit) than conventional assays, and can measure cTn concentrations in at least 50 % of a reference ...

POCT of NT-proBNP in patients with renal disease
Point of care (POC) testing has become an important part of nephrological care. In cases of acute renal failure, POC is indispensible in deciding the need for dialysis, but is also essential in the management of patients on regular dialysis.
For example, hyperhydration, cardiovascular adverse events and inflammation...

Point-of-care creatinine testing in radiology
The necessary administration of image-enhancing agents to patients prior to radiological investigation is associated with risk of two serious adverse effects: nephrogenic systemic fibrosis (NSF) and contrast-induced nephropathy (CIN). The risk only applies to those patients with renal disease, either acute kidney...

L-lactate and D-lactate - clinical significance of the difference
Modern blood gas analyzers often have incorporated sensor technology that allows measurement of plasma lactate concentration. In nature lactate exists in two isoforms: L-lactate and D-lactate.
In all vertebrates, including humans, the L-lactate form is by far the most abundant and pathophysiologically significant,...

Anemia treatment in CKD
Anemia, which is defined as hemoglobin (Hb) concentration
The kidneys are essential to the regulation of red-cell production and thereby maintenance of normal Hb concentration because the hormone erythropoietin, which regulates red-cell production, is synthesized in the kidneys. The usually normochromic, normocytic...

Use of tri-sodium citrate in hemodialysis
Hemodialysis and related treatments for those with failing kidneys all involve blood flow through a circuit outside the body. This extracorporeal circuit - the dialysis machine and its connections from and back to the body - is a non-physiological, pro-coagulant environment.
To counter the tendency for patients'...
