Ideal Conditions for Urine Sample Handling, and Potential in Vitro Artifacts Associated with Urine Storage
Urinalysis Made Easy: The Complete Urinalysis with Images from a Fully Automated Analyzer A. Rick Alleman, DVM, PhD, DABVP, DACVP Lighthouse Veterinary Consultants, LLC Gainesville, FL Ideal conditions for urine sample handling, and potential in vitro artifacts associated with urine storage 1) Potential artifacts associated with refrigeration: a) In vitro crystal formation (especially, calcium oxalate dihydrate) that increases with the duration of storage i) When clinically significant crystalluria is suspected, it is best to confirm the finding with a freshly collected urine sample that has not been refrigerated and which is analyzed within 60 minutes of collection b) A cold urine sample may inhibit enzymatic reactions in the dipstick (e.g. glucose), leading to falsely decreased results. c) The specific gravity of cold urine may be falsely increased, because cold urine is denser than room temperature urine. 2) Potential artifacts associated with prolonged storage at room temperature, and their effects: a) Bacterial overgrowth can cause: i) Increased urine turbidity ii) Altered pH (1) Increased pH, if urease-producing bacteria are present (2) Decreased pH, if bacteria use glucose to form acidic metabolites iii) Decreased concentration of chemicals that may be metabolized by bacteria (e.g. glucose, ketones) iv) Increased number of bacteria in urine sediment v) Altered urine culture results b) Increased urine pH, which may occur due to loss of carbon dioxide or bacterial overgrowth, can cause: i) False positive dipstick protein reaction ii) Degeneration of cells and casts iii) Alter the type and amount of crystals present 3) Other potential artifacts: a) Evaporative loss of volatile substances (e.g.

KETON.Zemia and KETONURIA in CHILDHOOD. by MURIEL J
Arch Dis Child: first published as 10.1136/adc.1.5.302 on 1 January 1926. Downloaded from KETON.zEMIA AND KETONURIA IN CHILDHOOD. BY MURIEL J. BROWN, M.B., Ch.B., D.P.H., AND GRACE GRAHAMI, AM.D. From the Medical Department, The Royal Hospital for Sick Children, Glasgow. The formation of ketone bodies and their excretion in the urine in albnormall amounts have for many years been problems of much interest to both physiologist and clinician. Much of our present knowledge of the subject has been gained from the study of carbohydrate metabolism in diabetes, where ketonuria in its classical formi is frequently observed. From this it has been established that an excess of ketone bodies occurs in the blood when the fats are incompletely ' combusted ' as a result of abnormal carbohydrate metabolism, and ample justification has been provided for the well-known sta.tement myiade by Rosenfeld(l) in 1895 ' that fat burns only in the fire of carbohydrate.' A good review of our present knowledge of ketone production and its prevention is to be found in Shaffer's recent lecture entitled ' Antiketo- genesis, its Mechanism and Signifiecance. '(2) A fu-ll discussion of the stubject in all its aspects is not within the scope of the present communication, but we may quote that ' there no Shaffer's statement is to-day question that http://adc.bmj.com/ ketosis is due to carbohydrate starvation,' and make special reference also to his remninder that the inhibitory effect of carbohydrate on ketone formation depends, not on the mnere existence of sufficient glucose, as glucose, in the blood (cf.

Prevalence of Ketosis, Ketonuria, and Ketoacidosis During Liberal Glycemic
Luethi et al. Critical Care (2016) 20:297 DOI 10.1186/s13054-016-1462-7 RESEARCH Open Access Prevalence of ketosis, ketonuria, and ketoacidosis during liberal glycemic control in critically ill patients with diabetes: an observational study Nora Luethi1, Luca Cioccari1,2, Marco Crisman1,3, Rinaldo Bellomo1,4, Glenn M. Eastwood1 and Johan Mårtensson1,5* Abstract Background: It is uncertain whether liberal glucose control in critically ill diabetic patients leads to increased ketone production and ketoacidosis. Therefore, we aimed to assess the prevalence of ketosis, ketonuria and ketoacidosis in critically ill diabetic patients treated in accordance with a liberal glycemic control protocol. Methods: We performed a prospective observational cohort study of 60 critically ill diabetic patients with blood and/or urine ketone bodies tested in ICU. All patients were treated according to a liberal glucose protocol targeting a blood glucose level (BGL) between 10 and 14 mmol/l in a single tertiary intensive care unit in Australia. We measured quantitative bedside blood 3-beta-hydroxybutyrate (β-OHB) and semi-quantitative urine ketones on ICU admission and daily during ICU stay, for a maximum of 10 consecutive days. Results: Median blood β-OHB level on admission was 0.3 (0.1, 0.8) mmol/l. Ketoacidosis was rare (3 %), but some level of ketosis (β-OHB ≥0.6 mmol/l) was found in 38 patients (63 %) early during their ICU stay. However, there was no significant difference in prevalence or severity of ketonemia and ketonuria among patients with BGL above (permissive hyperglycemia) or below 10 mmol/l. On multivariable linear regression analysis there was no association between blood ketone levels and BGL, HbA1c, lactate levels, hematocrit, catecholamine infusion or APACHE III score.

Fasting ketonuria is common during normal pregnancy, while there is evidence that it is increased among pregnant women with Gestational Diabetes Mellitus (GDM) who are on a diet. 3HB levels have been related to impaired offspring psychomotor development. Reports with concomitant measurement of blood and urine ketones in women with GDM who followed a balanced diet are lacking. OBJECTIVE: To compare the prevalence of fasting ketonemia and ketonuria in women with GDM following the Institute of Medicine diet instructions and assess their possible relation with metabolic parameters and therapeutic interventions. RESEARCH DESIGN AND METHODS: 180 women with GDM were studied. In each patient, in successive visits, capillary blood and urine ketones were simultaneously measured. The total measurements were 378, while the average number of measurements per patient was 2.1. RESULTS: The prevalence of ketonuria was significantly higher than that of ketonemia (x2=21.33, p <0.001). Significantly higher mean 3HB levels were observed with respect to ketonuria severity (p=0.001). Bedtime carbohydrate intake was associated with significantly lower 3HB levels (p=0.035). Insulin treatment was associated with significant 3HB levels reduction (p=0.032).

What Tells Routine Urine Examination
What tells Routine Urine Examination Specific gravity Animals producing large volume of urine have low specific gravity where as very small volume of urine has high specific gravity (animal with oliguric acute intrarenal failure that has a low urine volume and low specific gravity). Fluid therapy, diuretics, glucocorticoids and diet affect urine specific gravity. Sp. gr. is higher in morning samples and was observed to decrease as the age of the animal increased. Urine pH Acidic urine: - ingestion of meat, respiratory and metabolic acidosis, severe vomition, severe diarrhea, starvation, pyrexia, other protein catabolic states and administration of urinary acidifiers. Alkaline urine:- recent meal, ingestion of alkali, UTI with urease-producing bacteria, renal tubular acidosis, diets rich in vegetables and cereals, and metabolic and respiratory alkalosis, urine allowed to stand open to air at room temperature. Proteinuria Trace or 1+ protein level is considered normal with a specific gravity greater than 1.035. Highly alkaline urine (>8) can produce a false positive result. The most common cause of inflammatory proteinuria is urinary tract infection (UTI). If hematuria and pyouria is ruled out, then another urinalysis should be performed to determine the persistent proteinuria. Transient proteinuria is due to strenuous exercise, fever, seizures, and venous congestion of the kidneys and it is insignificant. Persistent proteinuria is usually due to glomerulonephritis or amyloidosis. The urine protein: creatinine ratio helps to determine the magnitude and significance of proteinuria. Glucosuria False negative results come due to large quantity of ascorbic acid, contaminated with H2O2, Cl, hypochlorite, formaldehyde or fluorides in urine. Cats with cystitis may give a false positive reaction.
