What is the approximate normal level of haematocrit/packed cell volume in men?

What is the approximate normal level of haematocrit/packed cell volume in men? Correct Answer 40% to 50%

Explanation:

  • Hematocrit is the percentage of red blood cells in the blood.
  • In men normal range is 40-50% (Specifically 40.7-50.3%).
  • In females, the normal range is 36%-48%.​

Additional Information

  • The function of the RBC is to transfer oxygen from lugs to tissues.
  • So the hematocrit level is important to measure the capacity of delivering oxygen.

Testing Method:

  • It is calculated by an automated analyzer.
  • Hematocrit is calculated by multiplying the red cell count by the mean cell volume.
  • The PCV can be assessed by heparinized blood at 10,000 RPM for five minutes.
  • Another method of assessing hematocrit is by optical methods such as spectrophotometry.

​Important Points

  •  It is also known as
    • Packed cell volume.
    • Volume of packed red cells.
    • Erythrocyte volume fraction.

A company paid Rs. 6,00,000 as bonus to its employees at different levels A, B and C. Each employee at level A receives one and half times of the amount that was paid to each employee at level B and each employee at level B was paid twice the amount paid to the employee at level C. If 50 employees were on level A, 75 on level B and 100 on level C, how much amount was paid to each employee of level A ?

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ the passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1.  Women CEOs face more negative backlash over ethics violations compared to male leaders. P. Thus men are considered more culpable in business failings, and that women are more nurturing than men, which makes them more at fault in actions that harm or disappoint others. Q. The findings expose some of society’s most rigidly ingrained stereotypes — that men are more competent than women. R. By contrast, the study also found a reverse gender bias in the public’s perception of business leadership: women leaders faced less flack for failures of competence than men. S. The findings are part of a broader slew of recent research focused both on evaluating the performance of male versus female business leaders (women tend to come out on top), as well as the public perception of male leaders v/s female leaders. 6. Perhaps, slowly, we’re realizing men should be as responsible for ethical conduct as women — which means we may not be far off from considering women just as competent as men.

The fasting blood sugar level (F) and the post prandial blood sugar level (PP) of a patient was monitored for four weeks W1, W2, W3, W4, and the readings (in mg/dl) for the four weeks are as follows: F/PP: 170/220, 150/180, 120/150, 90/120. These have been presented through a bar graph. The normal range is considered to be: F/PP: 70-100/100-130   During which week was the fasting blood sugar level of the patient approximately 115.4% above the upper limit of normal PP blood sugar level?
In the following question, two statements are numbered as Statement I and II. On solving these statements we get Quantity A and B respectively. Solve the given statements for both quantities and choose the correct option. Statement I: 5 men can finish work in 25 days. After 12 days, 2 workers have fallen sick. How much approximate time does it take to finish the work by remaining workers? Statement II: 12 men can finish a work in 28 days and 10 women can finish the same work in 30 days. What is the approximate time taken by 7 men and 5 women to finish this work?
The following questions have three statements. Study the question and the statements and decide which of the statement(s) is/are necessary to answer the question. In a certain election, total 480 men and 385 women voted for the winning candidate. Find the total number of men and women who voted in the election. Statement I∶ The ratio of number of men and women who voted in the election is 12 ∶ 11. Statement II∶ 100 more men than total women have voted in the election.  Statement III∶ 40% of the men and 35% of the women voted for the winning candidate. 
A private company entrusts work to 20 men working 12 hours a day. This group can complete the work in 24 Days. The company now wants to entrust twice the work to 60 men working 4 hours a day. Assume that 2 men of the first group do as much work in one hour as 3 men of the second group in 1 and 1/2 hours. How much number of days will the second group of men take to complete this work?
In a factory, there are equal number of men and children. Men work 9 hours a day and children work 6 hours a day. In festive season, the work load goes up by 60%. Due to restriction on children, they can only work 6 hours a day. So the extra work is done by men. If the men and children are equally efficient, then what extra work hours are out on men every day?
