"Should You Avoid Using Morning Urine for Urinalysis in a Pre-employment Physical? What Are the Unqualified Items That Could Prevent Job Entry in a Pr
Reasons for Not Using Morning Urine for Pre-employment Physical Examination:
1. High Concentration of Urine
Morning urine accumulates metabolic waste for a long time during the process of excretion of waste by the kidneys. It has a complex chemical composition, containing substances such as uric acid, urea, nitro, albumin, creatinine, etc. Urine tests in pre-employment physical examinations are usually used to assess renal function and metabolic status. Using morning urine may affect the results of the assessment.
2. Impact on the Accuracy of Results
Morning urine is the accumulation of urine over a long period after urination, and may not reflect the characteristics of normal urine. Using morning urine may affect the accuracy of test results.
3. Increased Measurement Error
The concentrated urine components in morning urine may lead to increased measurement errors in some items, further affecting the accuracy of results. For example, renal function indicators such as creatinine and uric acid in morning urine may be disturbed, making it difficult to accurately reflect the actual renal function.
Disqualifying Items in Pre-employment Physical Examination:
Hematology Diseases
Hematology diseases are a disqualifying item in pre-employment physical examination. Having pure iron deficiency anemia or abnormal hemoglobin levels can affect normal employment.
Urine Routine Examination
Urine routine examination includes tests for urine protein, red blood cells, urine occult blood, high uric acid, high urine ketone bodies, and high leukocyte levels. Disqualification in urine routine examination will prevent employment. Urine routine examination can reflect the health status of the kidneys and urinary system, and timely treatment can avoid serious consequences.
ECG (Electrocardiogram)
ECG is a mandatory item in pre-employment physical examination as it reflects the health status of the heart. Disqualifying conditions include sinus arrhythmia, pure left or right ventricular high voltage, myocarditis, congenital heart disease, coronary heart disease, etc. Abnormal ECG may indicate heart disease or other health issues and require further examination and treatment.
Hearing Impairment
Hearing impairment is a disqualifying item in pre-employment physical examination. If both ears have hearing impairment and the individual cannot hear within a distance of three meters even after wearing a hearing aid, they will be rejected by employers. Therefore, if there are hearing issues in the pre-employment physical examination, individuals should consult a doctor promptly and take appropriate measures to improve their hearing.
Vision
Disqualification in vision tests in pre-employment physical examination prevents employment. According to current corporate regulations, employees generally need to meet certain visual requirements, such as wearing corrective lenses. If vision exceeds 4.8, corrective lenses can be worn. However, vision tests are generally conducted only once, and if the position has special requirements, additional vision tests may be required. Therefore, failure in vision tests may lead to employees not meeting the employment conditions.
Tuberculosis
Tuberculosis is a disqualifying condition, but the following situations are qualified:
(1) Primary tuberculosis, secondary tuberculosis, and tuberculous pleurisy, which have been clinically cured and stable for 1 year with no changes;
(2) Extrapulmonary tuberculosis: renal tuberculosis, bone tuberculosis, abdominal tuberculosis, lymphatic tuberculosis, etc., which have been clinically cured for 2 years with no recurrence and no changes after examination by a specialized hospital.
