Wow, who'd a thought! --Bob Palin 21:21, 12 Feb 2004 (UTC)

Not to rain on any parades, but there's a certain amount of overlap with Reference ranges for common blood tests - Nunh-huh 06:28, 15 Feb 2004 (UTC)

Table and list

Is there any particular reason why there are two widely overlapping lists on this page? One is in a table, the other in a bulleted list. How come? --Diberri | Talk 22:19, May 20, 2004 (UTC)

• It's because the bulleted list doesn't specify if the numbers are for whole blood or plasma/serum and I haven't gotten around to move the last part of the list into the table yet. Fuelbottle | Talk 01:55, 21 May 2004 (UTC)

Duly noted. --Diberri | Talk 08:44, May 21, 2004 (UTC)

No normal

In some cases, take ethanol for example, there is no 'normal' (background) quantity listed. Natural values should be listed for these too. —Preceding unsigned comment added by 69.229.123.10 (talk) 08:58, 6 December 2009 (UTC)

Table

In the table Erythrocytes are showing measurements such as 5.2 (4.6-6.2) × 10^9 g/cm^3.

That's approaching the density of a black hole!

Should these all be 10^-9 ??? (Note the minus before the 9.)

The usual unit is millions of cells per microliter of blood. - Nunh-huh 03:47, 24 April 2012 (UTC)

If this is a cell count, then we need a different column in the table. The entries are in the column marked g/cm^3. MikeVdP (talk) 18:21, 24 April 2012 (UTC)

It's definitely a cell count. You'd use weight (grams) per volume to measure hemoglobin, not erythrocytes. The heading in the left column indicates "Erythrocytes (#/cm³)", which is number of cells per cc. Per Harrison's Internal Medicine, the adult range is 4.13-4.90 x 10¹² cells per liter. (which of course will vary with sex, race, age, and state of health)

Check my math, but these should all be equivalent:

4.13 x 10¹² cells per liter

4.13 x 10⁹ cells per cc

4.13 x 10⁶ cells per µl

4.13 million cells per microliter

Merge List of human blood components to Reference ranges for blood tests

Components or constituents ?

I suggest changing the name to Blood constituents, because the phrase "Blood Components" is used in a very specific connotation, at least in medicine. It means separating whole blood into easily separable components that can be supplied individually as transfusable units eg Packed RBCs, Platelet (or sometimes "platelet concentrate", (somewhat similar but different in application from Platelet-rich plasma which can be either a precursor component of platelet concentrate or a small scale version of platelet concentrate used for local injection) units that come as "random donor" and apheresis , Fresh frozen plasma or FP24. When these major components are further fractionated eg (cryoprecipitate) the first few steps might retain the term components, but on further processing and pooling they lose the stamp of blood component (but blood products of course) eg Human serum albumin, IVIG, etc. Blood component separation is a major subdivision of transfusion medicine. --Dr.saptarshi (talk) 14:51, 7 October 2012 (UTC)

Constituents can be cellular or acellular.. This article seems to be concentrating only on the acellular constutuents.. So the name might even be changed to list of acellular blood constituents.. But constituents are supposed to be what is present physiologically.. Does aluminium fall under that ? Tolerance levels of toxic substances is an altogether different subject.. those are neither reference levels nor physiological constituents ! Also, is this article the list of major constuents of human blood ? or mammalian blood ? Is it only about the adults or also includes fetuses ? If it includes fetuses then it should includes different types of fetuins as well. ;)--Dr.saptarshi (talk) 15:01, 7 October 2012 (UTC)
